Could changing a password terminate useful sessions?¶

Yes. Providers may revoke tokens and require some or all devices to authenticate again, permanently removing live access and visible session context.

Sessions can contain current evidence¶

Record account, active session, linked devices, recent sign-ins and session management before reset. A session may expose messages, cloud data, administration and security events.

Service behaviour varies: some sessions end immediately, others later or not at all. A session that survives is itself useful evidence about token policy, not proof of legitimate use.

Contain narrowly where possible¶

Consider preserving provider records or revoking one risky session before changing all credentials. If urgent reset is necessary, capture the original account and record which sessions ended, remained or displayed warnings.

Terminated account access does not identify the former controller; provider and device evidence are still required.
