Hi, by now it seems to be common knowledge that passwords shouldn't be stored in a database. Backend devs generally know to hash and salt and what-not their transmitted passwords. It seems to be well documented.

However, I wasn't exactly able to find such a clear answer for client applications accessing e.g. web APIs. For example, lets assume you were to create a Lemmy desktop application with support for multiple accounts. Ideally, that software would work like a password manager and store its master password as hash only.

However(2), sometimes users like to start said application without entering their password. Like an Email client in pleb mode. Which requires the passwords to be stored somewhere. In this case, what is the best course of action?

Pretty much every OS has some solution to this called a keyring, e.g.:

These can be used to basically delegate that job to somebody else. They typically work by protecting the keyring contents with the user's system credentials.
