What is two-factor authentication?
When logging in to your account, you must "know something" — your passphrase (or passcode). If someone was to ever figure out what that "something" is, they would be able to access your account.
Two-factor authentication adds an additional layer of security by requiring you to "have something" — usually a mobile device that provides a time-based code.
So, logging in is based on two-factors: knowing something (passphrase) and having something (your mobile device).
How two-factor authentication works in Peerio
With two-factor authentication enabled, Peerio will require you to enter an authentication code from your mobile device at least once a day, per public IP address.
If your IP address changes, such as traveling from home to work, you will be prompted to enter a new authentication code.

Don't have an authenticator app?
Peerio recommends using either:
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.

If you are using a Windows phone, we recommend using Microsoft Authenticator.
