Where Microsoft Authenticator fits
Choose it when work or personal services require a compatible authentication app.
Check before you choose
Confirm your organization's enrollment procedure and recovery path before changing devices.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
An authenticator protects a sign-in workflow, while encryption protects stored data. Both require recovery planning: losing a phone or an encryption key can make your own information inaccessible.
