Chrome's password manager allows for users to view their saved passwords on passwords.google.com. The saved passwords can be viewed on different devices as long as the user logs into their Google account. So, these passwords must be stored in a Google database. Is it known as to whether the passwords are encrypted in this database, so that Google wouldn't be able to know what your account passwords are?
If you can see a password (in plain text), it cannot have been hashed. The definition of hashing is that this process is irreversible. An alternative, less secure way, to store passwords is to encrypt them. The problem is that you can decrypt passwords, but depending on your use case, this could be a feature and not a bug.
How Google Chrome saves your passwords depends on whether you want to store and use them across devices. When synchronization is turned on for passwords in Google Chrome, your passwords are saved to your Google Account. Otherwise, your passwords are only stored on Google Chrome on your computer.
Not hashing passwords is not a best security practice, but depending on your use case encryption could be acceptable in combination with other security measurements to prevent unauthorized access.
When syncing my passwords from Google to a new device, it asks me for a specific passphrase I chose for it (not my current Google password) and states that it was used to encrypt the password DB.
This makes me believe that the password DB is actually encrypted and decrypted only on the client side. Also, quote from the passwords.google.com website:
You have secured your Chrome data with a sync passphrase. You can access your data within Chrome on your syncing devices, but not from this website.
This can be checked by reverse engineering Chrome.
