Where iMessage, WhatsApp, Signal, Telegram, Messenger and more stand now. canonical: https://relic.space/blog/which-messaging-apps-are-end-to-end-encrypted source: https://relic.space/llms.txt --- [Clipboard security & privacy](https://relic.space/blog/topics/clipboard-security) # Which messaging apps are end-to-end encrypted in 2026 Two things changed in May 2026\. Texts between iPhones and Android phones started getting end-to-end encryption, and Instagram took it away from DMs. So the list of which chat apps are private looks different now. This page checks each big one as of September 2026, with a source for every claim. [JGJordan Gibbs](https://relic.space/authors/jordan-gibbs) September 25, 2026 8 min read ## Which messaging apps are end-to-end encrypted? As of September 2026, these are end-to-end encrypted by default: * iMessage, Signal and WhatsApp (messages and calls). * Facebook Messenger, for personal chats and calls. * RCS texts between Google Messages users, and between iPhone and Android if both carriers support it. These are not: plain SMS, Telegram’s normal chats, Instagram DMs, Discord text, Slack, Teams chat and regular email. | | Encrypted end to end by default? | The catch | | ----------------------- | -------------------------------- | --------------------------------------------------------------------------- | | iMessage (blue bubbles) | Yes | iCloud Backup keeps a copy of the key unless Advanced Data Protection is on | | RCS, iPhone and Android | Yes, in beta since iOS 26.5 | Both carriers must support it. Look for the lock | | RCS, Android to Android | Yes, in Google Messages | Everyone in the chat needs Google Messages with RCS on | | SMS and MMS | No | Never encrypted end to end | | WhatsApp | Yes, chats and calls | Backups only if you turn on encrypted backup | | Signal | Yes, everything | Nothing to switch on | | Telegram | No | Only Secret Chats, which are one-to-one and stay on one device | | Facebook Messenger | Yes, personal chats and calls | Meta's rollout began in December 2023 | | Instagram DMs | No | The opt-in version was removed on May 8, 2026 | | Discord | Calls yes, text no | Stage channels are left out | | Slack | No | Encrypted on the way and on Slack's servers only | | Microsoft Teams | No, for chat | 1:1 calls and meetings can be, if the admin allows it | | Gmail and most email | No | Protected in transit. Work accounts can add more | ## What an encrypted message means Almost every app encrypts your messages on the way to its servers. That stops a stranger on the same Wi-Fi from reading them. But the company unlocks them when they arrive, so the company can read them. End-to-end encryption goes further. Your phone locks the message before it leaves, and only the other person’s phone has the key to open it. The app company carries the locked message and can’t open it. When a chat app shows a lock icon or says a chat is “end-to-end encrypted”, that’s the promise. Our [plain-English guide to end-to-end encryption](https://relic.space/blog/what-is-end-to-end-encryption) covers how the keys work. On this page we only ask one thing: can the company in the middle read your chat? ## Is iMessage end-to-end encrypted? Yes. Blue-bubble iMessage chats between Apple devices are end-to-end encrypted. [Apple’s support page](https://support.apple.com/en-us/104972) says they “can’t be read while they’re sent between devices”. The weak spot is the backup. If you use Messages in iCloud and iCloud Backup is on, Apple’s [iCloud security overview](https://support.apple.com/en-us/102651) says the backup includes a copy of the key for your messages. Apple stores that key, so Apple could unlock your messages. Turning on Advanced Data Protection fixes this. With it on, the backup and the key inside it are end-to-end encrypted too. The trade-off is on [Apple’s setup page](https://support.apple.com/en-us/108756): Apple no longer has the keys to help you recover your data. You’ll need your device passcode, a recovery contact or a recovery key instead. ## Are iPhone to Android texts encrypted now? Yes, if the pieces line up. Apple released iOS 26.5 on May 11, 2026, and [its announcement](https://www.apple.com/newsroom/2026/05/end-to-end-encrypted-rcs-messaging-begins-rolling-out-today-in-beta/)says end-to-end encrypted RCS “begins rolling out in beta” that day. RCS is the newer texting standard that replaces SMS between iPhones and Android phones. The encryption comes from RCS Universal Profile 3.0, which [MacRumors reports](https://www.macrumors.com/2026/05/04/ios-26-5-rcs-encryption/)Apple helped write. It’s built on an open standard called Messaging Layer Security (MLS). For a green-bubble chat to be encrypted, all of these need to be true: * The iPhone is on iOS 26.5 or later. * The Android phone has the latest version of Google Messages. * Both people’s carriers support encrypted RCS. Apple’s [page on bubble colors](https://support.apple.com/en-us/104972)is blunt about this: the encryption of each chat “depends on whether your contact’s carrier also supports it”. * The switch is on. It’s on by default. On the iPhone it lives in Settings > Apps > Messages > RCS Messaging > End-to-End Encryption. When it works, you see a small lock in the chat. To be sure, tap the name at the top of the chat and scroll down. [9to5Mac found](https://9to5mac.com/2026/05/27/ios-26-5-gave-messages-app-encrypted-rcs-heres-how-to-check-its-working/)an encrypted chat says “This conversation is encrypted end-to-end” at the bottom. Apple says older chats switch over “over time”, so a chat without the lock today may get it later. We’d still treat any green bubble as readable until you see the lock yourself. ### Android to Android This part isn’t new. Google’s [Messages help page](https://support.google.com/messages/answer/10252671?hl=en)says RCS chats between Google Messages users are upgraded to end-to-end encryption on their own. That covers one-to-one and group chats, as long as everyone in the chat uses Google Messages with RCS turned on. A lock on the send button tells you it’s working. ### Plain SMS SMS and MMS are never end-to-end encrypted. Apple says they’re “not protected from a third-party reading them” on the way. Your carrier can read them. A green bubble with no lock may be SMS, so don’t send a password or a bank detail that way. ## WhatsApp and its backups WhatsApp encrypts personal chats end to end by default. Its [privacy page](https://www.whatsapp.com/privacy) lists messages, photos, videos and calls. Its [calling page](https://www.whatsapp.com/calling)says calls “are always end-to-end encrypted”, and that includes video calls. Backups are different. WhatsApp saves your chat history to iCloud or Google Drive, and those copies are only end-to-end encrypted if you ask for it. Go to Settings > Chats > Chat backup > End-to-end encrypted backup. Since [October 2025](https://about.fb.com/news/2025/10/making-it-easier-to-encrypt-whatsapp-chat-backups/)you can lock it with a passkey (your face, fingerprint or screen lock) instead of a password or a 64-digit key. If you’ve never opened that menu, your backup probably isn’t end-to-end encrypted. That’s the single most useful thing on this page to go check. ## Signal Signal encrypts every message and every call, and there’s no setting to turn it off. Its [support page](https://support.signal.org/hc/en-us/articles/360007320391-Is-it-private-Can-I-trust-it)puts it as “every message, every call, every time”. Signal also keeps very little about you. When it gets a subpoena, its [published responses](https://signal.org/bigbrother/)show it can only hand over the date you signed up and the last date you connected. If you want the most private option on this list, it’s Signal. ## Is Telegram encrypted? Not end to end, unless you start a Secret Chat. Telegram’s own [FAQ](https://telegram.org/faq)splits chats in two. Normal “cloud chats”, which is every chat you start by default and every group, are encrypted between your phone and Telegram’s servers. Telegram holds the keys to them. That’s how your chats show up on a new phone or on your laptop. Secret Chats are end-to-end encrypted. They only work between two people, and they stay on the device where you started them. You won’t see them on your other devices. Voice and video calls on Telegram are end-to-end encrypted. A lot of people assume Telegram is the private one. For everyday chats, WhatsApp and Signal protect you more. ## Messenger and Instagram Meta started turning on end-to-end encryption by default for personal chats and calls on Messenger and Facebook in [December 2023](https://about.fb.com/news/2023/12/default-end-to-end-encryption-on-messenger/). It said the global rollout would take months. When your chats are upgraded, Messenger asks you to set a recovery PIN so you can get your history back on a new phone. Instagram went the other way. Encrypted DMs there were opt-in, and you had to switch them on one chat at a time. Starting May 8, 2026, Instagram removed the option. Meta’s explanation, as [MacRumors reported](https://www.macrumors.com/2026/05/08/instagram-end-to-end-encryption/), was that “very few people were opting in”. People with encrypted chats were told how to download what they wanted to keep. So as of September 2026, treat every Instagram DM as something Meta can read. Meta itself pointed people who want encryption to WhatsApp. ## Discord, Slack and Teams Discord now encrypts every voice and video call end to end. That covers DMs, group DMs, voice channels and Go Live streams, but not Stage channels. Text chats are not. In its [May 2026 post](https://discord.com/blog/every-voice-and-video-call-on-discord-is-now-end-to-end-encrypted), Discord says it has “no current plans to extend E2EE to text messages”. Work chat apps aren’t built for this at all. Slack says [customer data is encrypted at rest and in transit](https://slack.com/trust/security), which means it’s locked on the way and on Slack’s servers. That isn’t end to end. Microsoft Teams has an [end-to-end option](https://learn.microsoft.com/en-us/microsoftteams/teams-end-to-end-encryption)for one-to-one calls and for meetings. It’s off by default for calls, your admin has to allow it, and encrypted meetings need a Teams Premium license. It doesn’t cover chat messages. On a work account, assume your company can get to your chats. ## Gmail and email Regular email is not end-to-end encrypted. Gmail says [all Gmail messages use TLS](https://support.google.com/mail/answer/6330403?hl=en), which protects them on the way between mail servers. Google can still read them, and so can the other person’s email provider. Work and school accounts can add S/MIME, where Google still holds a copy of the key, or client-side encryption, where only the organization does. A personal Gmail account has neither. ## What end-to-end encryption doesn’t hide A lock icon protects the message while it travels. These gaps stay open: * **Backups.** iMessage and WhatsApp both have the backup gap above. The [EFF notes](https://www.eff.org/deeplinks/2026/05/victory-end-end-encrypted-rcs-comes-apple-and-android-chats) that Google Messages encrypts the text of messages in backups, but not the photos and videos. * **Who and when.**The EFF also warns that for encrypted RCS, “metadata will likely still be collected and stored”. That’s who you talked to and when. For that, it points to Signal. * **The other person’s phone.**Once your message arrives, it’s theirs. They can screenshot it, forward it, or back it up somewhere that isn’t encrypted. * **Your own phone.** Anyone who can unlock it can read your chats. So can malware running on it. For a password or a card number, don’t leave it sitting in any chat history. A [one-time private note](https://relic.space/tools/private-note) (our free tool) is encrypted in your browser and deleted after one read.

WhatsApp says calls on WhatsApp are always end-to-end encrypted, and that covers voice and video calls. You don't need to turn anything on. Why did Instagram remove end-to-end encryption?+ Meta said very few people were turning it on. Encrypted DMs on Instagram were opt-in and had to be switched on one chat at a time. Instagram started removing the option on May 8, 2026\. People who had encrypted chats were told how to download what they wanted to keep. Meta pointed people who want encryption to WhatsApp. Why don't I see a lock on my texts to an Android phone?+ Four things have to line up. You need iOS 26.5 or later. Your friend needs the latest Google Messages. Both of your carriers have to support encrypted RCS. And the setting has to be on, under Settings, then Apps, then Messages, then RCS Messaging. If the chat has fallen back to SMS, it can't be encrypted at all. Apple and Google say encryption turns on for existing chats over time, so a chat without the lock today may get it later. Does end-to-end encryption hide who I'm talking to?+ Usually not. It hides what you say. The service can often still see who you message and when. Signal keeps less of this than most: it says the only account data it can hand over is when you signed up and when you last connected.
