This is working as designed. New data will not sync to the other instances until you enter the current password, but old data will remain available.

To protect data on devices from compromise, use the security features provided by the operating system (e.g. user account passwords and full disk encryption). https://chromium.googlesource.com/chromium/src/+/master/docs/security/faq.md#Why-arent-physically_local-attacks-in-Chromes-threat-model

The idea of Working As Intended is NOT appropriate way to handle the situation. Have you thought about other ways to manage the situation. When the browser detects that the password is out of sync why is it still auto completing the passwords tied to an account? Should'nt this feature be disabled acknowledging the fact that the account is now out of sync? What precautions is the browser taking when it detects that the account out of sync? This issue is NOT about me finding my lost laptop. This is a security gap in how Chrome works.

Im agree with the last comment. Everybody knows that breaking a local windos password is a game of kids as my previous case, just using some tools of hirens boot,the local password could be changed in one second. So my logic is the next:

If google is providing me a feature to save my passwords in a "secure" way, why google says that the best way to protect the passwords is a password of the OS? Google should protect him by himself. I really lime microsoft but everybody with some thechnical skill knows the weakness of it.
And google products are amazing, why not improve this weakness we found just to be 100 percent sure about the product?
