Why add a second step
A password can be guessed, reused, or leaked. Two-factor authentication means a stolen password alone isn't enough to get into your account — you also need a code from an authenticator app on your phone.
Set it up
When prompted, scan the code shown with an authenticator app on your phone, then enter the 6-digit code it generates to confirm the two are linked.
Save your backup codes
Right after you enable two-factor authentication, you're shown a set of one-time backup codes. Save them somewhere safe — each one works once to get you signed in if you ever lose access to your authenticator app, and they're only shown this one time.
Signing in afterwards
From now on, after your password you'll be asked for the current code from your authenticator app. Turn on Remember this device for 30 days on a device you trust and use often, so you're not asked for a code every single time you sign in there.
If you can't access your authenticator app
Use one of your backup codes to sign in instead of a code from your app. If you've used them all or never saved them, contact your clinic's administrator, or support if you administer the account yourself, to have it reset.
