I prefer the option to use an authenticator app rather than receiving codes via text message whenever possible, and so should you. The reason is simple logistics.

Authenticator apps get around this problem by letting you generate your own verification code. That makes you less likely to be hacked, and more likely to recover your account if you are.

If your Microsoft Authenticator app is not working or displaying code for the accounts, then follow the suggestions to fix the issue using multiple methods.

Two-factor authentication is critical to securing your online accounts, and Duo Mobile offers the best combination of security, accessibility, and ease of use.

Microsoft Authenticator provides multi-factor authentication options, as well as a password manager. Here's what you should know about the app.

If the Microsoft Authenticator app doesn’t cover all your needs, support for FIDO2 hardware security devices is also coming. That could be a Yubikey, or even a fitness tracker like the Motiv Ring.

Overall, authenticator apps provide a simple yet powerful way to safeguard your digital identity and reduce the risk of account takeovers.
