What is two-factor authentication?

Two-factor authentication is an additional security measure you can add to your Peerio account.

Two-factor authentication requires two pieces of identification in order to access an account, traditionally one is a piece of information (e.g. a passphrase or passcode) and one is physical (e.g. a card or device). With Peerio, the first piece is your passphrase or passcode and the second piece is your mobile device.

When you have enabled two-factor authentication and attempt to login to Peerio for the first time in a day, or from another location, you will be asked to verify that the request is valid using an authenticator app on your mobile device. The app will display a six-digit code that changes every minute, to ensure that only you will have access to the code.

Peerio recommends using one of the following authenticator apps.:

Authy: Encrypted backup and sync of your accounts across devices, remote device de-activation, PIN-locking, and a desktop app. Provides convenience and security in the event of a stolen or lost device. Not open source. Available for Android, iOS, Blackberry, Chrome.

FreeOTP: A free and open-source authenticator. Simple and reliable. Available for Android and iOS.

Microsoft Authenticator: If you are using a Windows phone.

Even if your passphrase or passcode was somehow compromised, an intruder would not be able to access your account without your mobile device.
