According to the chromium documented cited, this is wrong.
According to the docs, the credentials are actually stored as plain text in the chrome profile if one is not using an external password manager.
And this is still true today.

You can also see that when using chromium - no one has to give a secret at any time to decrypt the passwords.

For many people an autoconnect for the password-manager-service would probably solve this
