But this is not safe. A better way is to treat the password as input to one operation: establishing a session. Here's how it works:

• You enter your credentials.
• Your service uses them to log in.
• Your service captures cookies and local storage from the browser context.
• Your service encrypts that session state and stores it.
• Your service discards the password.
• Future jobs load the encrypted session state instead of asking for the password again. You should never write the password to disk, never return it from an API, never log it, and never keep it as reusable application state. Session storage needs nearly the same controls as password storage. Every read should include tenant scope. Return handles and metadata, not secrets. Do not return encrypted session blobs to the frontend. For authenticated browser jobs, a good system treats expired sessions, rotated cookies, and changed passwords as normal states. Bad behavior looks like a timeout error. Better behavior distinguishes the failure and tells you what happened. Revocation should take effect before the next job starts. Logs can undo good database design. Use structured redaction by default. Do not reuse one persistent browser profile across users or tenants. Create a fresh context for each job, load only the specific session state needed, then tear it down.
