App password: a provider-issued credential with a specific lifecycle
An app password is a provider-issued credential for an eligible application connection. Availability and revocation rules depend on the provider and account policy.

Who this helps: Readers checking a term before making an outreach or mailbox decision.
Meaning and common confusion
For Google accounts, app passwords have eligibility requirements and can be revoked after a main account password change. Their absence is not a reason to disable account protections. Prefer the supported authorization path and have an administrator review policy when necessary.
Worked example

Main account password changes
Connection begins failing
Investigation: check credential revocation and the supported reconnection path
Do not expose either credential in an error screenshot.Checks to make
- Confirm the account supports the intended method.
- Use a distinct approved credential rather than sharing the main password.
- Verify both sending and receiving after replacement.
Next step and limits
Use the missing or revoked app-password guides for a specific failure. Do not assume every provider offers this mechanism or that it bypasses protocol restrictions. Store it as a secret and remove obsolete credentials through the provider's process.
