By asking Chrome to remember your master password, you have essentially defeated the security for the password manager. The encryption uses the windows encryption, which means if they can hack your windows account, they can decrypt the password. Once they have your master password, they can hack your password manager, though 2FA would slow them down.depending on which method you use for 2FA.
You should do 2 things:
- Type out your master password to a text file and save the text file to a USB key.
- Export your vault as a csv file and save it to the same usb key unencrypted.
Store the usb key something physically secure. A good place is your safety deposit box, but it could be hiding place, but don’t forget where you put it. The reason to store it unencrypted is in case you forget the key.
If you forget the master password, you can look it up. If you mess up and update your password to something unknown, you can use the vault backup to restore.
