The Microsoft Authenticator app has already started making some changes to how you handle your passwords, but it will no longer support passwords altogether on Aug. 1. In June, it stopped letting users create new passwords. In July, it turned off the autofill password function.

For years, Authenticator supported multi-factor authentication and password management. But going forward, it’ll be a new home for your passkeys, such as a PIN, fingerprint or facial recognition.

Attila Tomaschek, CNET’s software senior writer and digital security expert, said that’s not a bad thing, though. 

«Passwords can be cracked, whereas passkeys need both the public and the locally stored private key to authenticate users, which can help mitigate risks like falling victim to phishing and brute-force or credential-stuffing attacks,» Tomaschek said.

Passkeys get rid of the risky password habits practiced by 49% of US adults, like using the same password for multiple accounts or using personal hints, according to a CNET survey. However, those convenient hints can pose a bigger risk to scammers, identity theft and fraud. 

If you’re a fan of Authenticator and not sure where to start before the switch, here’s what you need to do before Microsoft’s Aug. 1 move. 

When will Microsoft Authenticator stop supporting passwords?

Microsoft Authenticator houses your passwords and lets you sign into all your Microsoft accounts using a PIN, facial recognition like Windows Hello, or other biometric data like a fingerprint. Authenticator can be used in other ways, such as verifying you’re logging in if you forgot your password, or using two-factor authentication as an extra layer of security for your accounts. In June, the company stopped letting users add passwords to Authenticator.

Starting this month, you won’t be able to use the autofill password function. And next month, you’ll no longer be able to use saved passwords.

If you still want to use passwords instead of passkeys, you can store them in Microsoft Edge. However, CNET experts recommend adopting passkeys during this transition. «Passkeys use public key cryptography to authenticate users, rather than relying on users themselves creating their own (often weak or reused) passwords to access their online accounts,» Tomaschek said.

Why are passkeys a better alternative to passwords?

So what exactly is a passkey? It’s a credential created by the Fast Identity Online Alliance that uses biometric data or a PIN to verify your identity and access your account. Think about using your fingerprint or Face ID to log into your account. That’s generally safer than using a password that is easy to guess or susceptible to a phishing attack.

Passkeys aren’t stored on servers like passwords. Instead, they’re stored only on your personal device. More conveniently, this takes the guesswork out of remembering your passwords and the need for a password manager.

How to set up a passkey in Microsoft Authenticator

Microsoft said in a May 1 blog post that it will automatically detect the best passkey to set up and make that your default sign-in option. «If you have a password and ‘one-time code’ set up on your account, we’ll prompt you to sign in with your one-time code instead of your password. After you’re signed in, you’ll be prompted to enroll a passkey. Then the next time you sign in, you’ll be prompted to sign in with your passkey,» according to the blog post.

To set up a new passkey, open your Authenticator app on your phone. Tap on your account and select «Set up a passkey.» You’ll be prompted to log in with your existing credentials. After you’re logged in, you can set up the passkey.
