Check the publication date and any correction or update note. An old report may describe a policy or product that has since changed.
Open the cited source and find the passage behind the claim. A working link means the page is available; it does not establish that the claim is supported.
Keep the source, date, and uncertainty with your share. If something is wrong or a source has moved, send the affected URL and supporting evidence through Contact.
Use a disposable example rather than a token that grants access to a real account. Keep credentials out of screenshots, support tickets, and public messages.
Treat the decoded header, claims, and expiry as assertions. A decoder does not establish who issued the token or whether its signature is valid.
For an application, use its established validation rules for the expected issuer, audience, key, and algorithm. Read the guide for the distinction between decoding and acceptance.
Open the linked-app settings for the correct Google account and inspect the connection type and permissions. Sign-in and access to account data are different relationships.
Remove connections you no longer need. Before removing a sign-in connection, check how you will access the other service afterward.
Review the other service separately for stored data and account deletion. Removing a connection is not evidence that previously shared information was erased.
