Why has my sign-in link or code expired?

Sign-in links and codes expire, and a new request replaces the previous one. An already used link cannot create another session. On the expired or used-link screen, choose Send a new code to request a fresh email for that sign-in attempt.

Use the latest email and follow the screen's instructions in the device or browser where you are signing in. Do not keep trying an old code or send it to support. If the fresh email does not arrive, report the screen and delivery problem without including any authentication secret.
