Wire does not sell analytics or usage data to anyone. Physical, electronic, and procedural safeguards are provided to protect your information. Wire stores only the data needed to ensure your conversations stay in sync across devices and troubleshoot issues. We’re transparent about the data we collect, and what we use it for. Wire uses end-to-end encryption for all messages, media, and calls, as well as Secure Real-Time Transport Protocol (SRTP) with Datagram Transport Layer Security (DTLS) for end-to-end calling encryption. See Wire’s Security Whitepaper and Privacy Whitepaper for more details about the encryption methods and how Wire protects your privacy. ID Shield End-to-end identity with ID Shield Wire’s ID Shield confirms you're speaking with the right contact. Device checks are automatic and based on certificates, removing the need for manual fingerprint comparisons while ensuring secure identity validation. Verify devices Trusted conversations Verify each conversation partner’s device fingerprints for maximum security. It helps to protect you from a man-in-the-middle attack by ensuring that the person you are communicating with is who they say they are. After verifying a conversation, you will be alerted if your contact starts using Wire on a new device. Stay in sync Multi-device management You can use your Wire account on up to 8 devices with your contacts and conversations always in sync. Log in to your Wire account on mobile, desktop, browser, or tablet to add another device to your device list. You can manage the devices associated with your account at any time. Frequently Asked Questions Why is Wire secure? Wire is a secure messaging app that uses end-to-end encryption (E2EE) for all communications—including messages, calls, and file sharing—ensuring only participants can decrypt the information. E2EE is always enabled by default and cannot be disabled. Wire's open-source code allows anyone to verify its security protocols. Message Encryption: Wire employs the Proteus protocol, its implementation of the Axolotl/Double Ratchet protocol, to secure messages between clients. By utilizing pre-keys, Wire allows encrypted conversations to start even when both parties are not online simultaneously. The Proteus protocol incorporates robust cryptographic primitives: ChaCha20 Stream Cipher HMAC-SHA256 for message authentication codes Curve25519 for elliptic curve Diffie-Hellman key exchange HKDF for key derivation functions Media Encryption : For one-to-one audio and video calls, Wire uses the Secure Real-time Transport Protocol (SRTP) , with encryption keys and parameters negotiated through a Datagram Transport Layer Security (DTLS) handshake. Client authenticity is verified via fingerprint exchange over authenticated Proteus sessions. Conference calls are similarly encrypted but leverage Insertable Streams for E2EE of media packets, using: AES-GCM 256 for payload encryption HKDF-SHA512 for key derivation Forward Secrecy (FS) & Post-Compromise Security (PCS): Wire ensures that all communications benefit from Forward Secrecy (FS) and Post-Compromise Security (PCS): Forward Secrecy (FS) : Even if an encryption key is compromised, past communications remain secure because each message is encrypted with a unique key. Post-Compromise Security (PCS) : After detecting a security breach and replacing compromised keys, future communications remain secure, safeguarding against attackers who had access to earlier sessions. See Wire’s Security Whitepaper for more technical details about the encryption protocols. Or visit our help center to get more details. Which data does Wire need? Wire is committed to user privacy by collecting only the minimal data necessary to sync conversations across devices and troubleshoot issues. User profiles include: Registration email Username Profile name Upon registration, Wire stores metadata per device to enhance notification clarity: Device class (mobile, tablet, desktop) Device model (for example, iPhone 14) User-defined device label Cookie label for authentication UTC timestamp of device registration For more details please see Wire’s Privacy Whitepaper . Does Wire protect against Man-in-the-Middle (MITM) attacks? Wire allows users to verify conversations by comparing unique key fingerprints for each client. This process ensures that you're communicating with the intended recipient and helps prevent man-in-the-middle (MITM) attacks. After verification, you'll receive alerts if your contact starts using Wire on a new device. Learn more about Wire’s crypto protocol How does Wire protect my data? Wire uses end-to-end encryption for all messages, media, and calling. We use Secure Real-Time Transport Protocol (SRTP) with Datagram Transport Layer Security (DTLS) for end-to-end calling encryption. Wire's mobile applications utilize operating system push notification services—Apple Push Notification Service (APN) for iOS and Firebase Cloud Messaging Service (FCM) for Android—to notify the app of updates. Importantly, Wire does not share any message or call data with these services. The app connects directly to Wire's servers to receive E2EE messages. Users preferring not to rely on external push services can download the F-Droid version of the Wire app, which avoids FCM and uses websockets for notifications. See Wire’s Security Whitepaper and Privacy Whitepaper for more details about the encryption methods Wire uses and about how Wire protects your privacy.
