With phone sign-in, we’re shifting the security burden from your memory to your device. Just add your account to the Android or iOS Microsoft Authenticator app, then enter your username as usual when signing in somewhere new. Instead of entering your password, you’ll get a notification on your phone. Unlock your phone, tap “Approve”, and you’re in.

This process is easier than standard two-step verification and significantly more secure than only a password, which can be forgotten, phished, or compromised. Using your phone to sign in with PIN or fingerprint is a seamless way to incorporate two account “proofs” in a way that feels natural and familiar.

Here’s how you set it up:

If you already use the Microsoft Authenticator for your personal account, select the dropdown button on your account tile, and choose Enable phone sign-in.
If you are adding a new account on an Android phone, we’ll automatically prompt you to set it up.
If you are adding a new account on an iPhone, and we’ll automatically set it up for you by default.
