When does a nonce in WordPress become invalid?
The other way a nonce can become invalid is if a user’s session token changes. That state change occurs when a user logs out and back in again. Since a new session token is generated, all previous nonces won’t validate anymore. To make things clearer, WordPress doesn’t store the nonce it creates for a user.
