simple_oauth_account_picker

Adds an account picker, similar to how Google does it, when authorizing a client application via the Authorization Code Grant.

This presents the user with the following options:

• Log in using the currently logged-in account (instant)
• Log in using another account the user has previously used to log in (prefills username on login form)
• Log in using a completely different account (takes user to empty login form)

Features

• Default style integrates with default Olivero theme.
• Automatically generates an avatar using the first letter of the account element title, if no image src is set via the alter hook.
• Automatically adds accounts the user previously logged in to drupal with to the account picker (via cookie)
• Ability to completely alter the account element (title, subtitle, avatar and the right text) via a hook.
• Works with the consumer options Automatic authorization and Remember previous approval
