How to Test OAuth Recovery Emails Without Exposing Real Inboxes

Short summary

OAuth recovery email testing requires per-test inbox isolation instead of shared mailboxes to prevent token reuse and data exposure. Verify that links expire, codes are single-use, subjects don't leak account data, and logs are redacted. Teams should implement a checklist covering inbox isolation, token invalidation, log redaction, and artifact cleanup to prevent account takeover via recovery paths.

• •Verify token expiry, single-use enforcement, and that recovery messages don't leak sensitive data in subjects or previews
• •Implement a security checklist covering inbox isolation, token invalidation, log redaction, and artifact cleanup
