Where Google Authenticator fits
Use it when a service asks you to enroll an authenticator rather than receive a text message.
Check before you choose
Review synchronization choices and retain the service's recovery codes separately.
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.
