Each code is valid for thirty seconds. A ring beside it counts down so you know whether to wait for the next one.
Live codes with their countdown rings.
Why this matters
No more switching apps to sign in β your one-time codes live right next to the login they belong to, encrypted with everything else. Your first one is free.
Steps
Open the side menu and tap Authenticator.
Find the account you are signing in to.
Tap the code to copy it.
Paste it into the website before the countdown runs out.
Good to know
If a code is rejected, wait for the next one and try again β your device clock may be slightly out.
Codes work offline. They are generated from the stored secret, not fetched.
