Add an authenticator app
An app-based code is the strongest everyday second step — it’s generated on your device and can’t be SIM-swapped like a texted one. On the Ways to prove who you are list, choose Add a new way to sign in or verify, then Use an app. Microsoft suggests its own app first — pick set up a different Authenticator app if you’d rather use Proton Authenticator or another app.
Open your authenticator app, scan the QR code Microsoft shows, then type the 6-digit code your app generates and choose Next. This adds the authenticator as a verification method — in the next step you’ll switch on two-step verification to make it required on every new sign-in.

We recommend Proton Authenticator
Strong one-time codes that can't be SIM-swapped like a text message — free, open-source, and they stay on your device.
Turn on two-step verification
Once it’s on, every sign-in on a device Microsoft doesn’t recognise needs your password and a code from your authenticator — so a stolen or guessed password is no longer enough on its own.

Save your recovery code
Treat it as a one-time, emergency-only code: it’s there for the day you’ve genuinely lost every other way in, and using it consumes it — you’ll need to generate a fresh one afterwards. Don’t reach for it during everyday sign-in.

Recovery code
You can use this code to access your account if you lose access to your sign-in info. Print this out and keep it in a safe place or take a picture of it.

Set a strong, unique password
Don’t try to invent or memorise it — let a password manager generate and store a long, random one for you. We recommend Proton Pass: it creates a unique password for every account and fills it in automatically, so ‘long and unique’ costs you no effort to keep up.

We recommend Proton Pass
Generate and remember a long, unique password for every account — free, open-source, and end-to-end encrypted.
Review your recovery and sign-in methods
With those two in place, remove Text a code (SMS) if it’s listed. Text messages can be intercepted or SIM-swapped, so it’s the weakest way to prove it’s you and you no longer need it — expand the method and choose Remove.

Can't remove it?

We recommend Proton Mail
Your recovery pathway is only as secure as the email it's attached to. For maximum security, we recommend an end-to-end encrypted inbox.
