[felixgao]

Describe the bug
The keyring must be a subclass of KeyringBackend

To Reproduce
Steps to reproduce the behavior:

1. poetry install keyring
2. add the following code

import keyring
from keyring.backends import OS_X
keyring.set_keyring(OS_X.Keyring)

3. run the script

Expected behavior
the keyring is set to OSX's keyring

Environment

• OS: OS X 10.15.7

$ pip list | grep keyring
keyring                   23.0.0
...
$ keyring --list-backends
keyring.backends.macOS.Keyring (priority: 5)
keyring.backends.fail.Keyring (priority: 0)
keyring.backends.chainer.ChainerBackend (priority: -1)
...

Additional context

The error message is incorrect. It should say "The keyring must be an instance of KeyringBackend". You need to pass an instance of the backend, i.e. keyring.set_keyring(OS_X.Keyring()). Also, be aware that since keyring 22 and later, you should prefer keyring.backends.macOS to keyring.backends.OS_X.

By the way, if you're on macOS, you don't need to set the keyring. It will be discovered automatically (based on the priorities).
