# Can't sign in

Lockouts, expired links, unverified accounts, and MFA trouble.

## In brief

- **Audience:** Everyone
- **Most common cause:** Throttle lockout

## Locked out after failed attempts

Ten failed attempts in 15 minutes locks sign-in for 15 minutes. The lock releases on its own — waiting is the fix, and support cannot lift it early.

## Verification or reset link doesn't work

Links are one-time and expire. Request a fresh one and use the newest email; older links in your inbox are already dead.

## Lost your authenticator

Use one of the recovery codes you saved at enrollment — each works once. Out of codes? An account owner can help re-establish access.

## Account is suspended or past due

Sign-in can be blocked by account state, not credentials. Builders: check [payment issues](../billing/payment-issues.html). End users: contact your administrator.
