   - When the current date and time is greater than a key's activation date, Azure AD B2C activates the key and stop using the prior active key.
 - When the current key's expiration time has elapsed and the key container contains a new key with valid *nbf (not before)* and *exp (expiration)* times, the new key becomes active automatically. New tokens are signed with the newly active key. It's possible to keep an expired key published for token validation until disabled by an admin, but this must be requested by [filing a support request](/azure/active-directory-b2c/find-help-open-support-ticket).
 
-- When the current key's expiration time has elapsed and the key container *doesn't* contain a new key with valid *not before* and *expiration* times, Azure AD B2C won't be able to use the expired key. Azure AD B2C raises an error message within a dependant component of your custom policy. To avoid this issue, you can create a default key without activation and expiration dates as a safety net.

 - The key's endpoint (JWKS URI) of the OpenId Connect well-known configuration endpoint reflects the keys configured in the Key Container, when the Key is referenced in the [JwtIssuer Technical Profile](./jwt-issuer-technical-profile.md). An application using an OIDC library will automatically fetch this metadata to ensure it uses the correct keys to validate tokens. For more information, learn how to use [Microsoft Authentication Library](../active-directory/develop/msal-b2c-overview.md), which always fetches the latest token signing keys automatically.
