Install

pip install oauth_tools

Example

from oauth_tools import AuthManager
import webbrowser
import creds
import os

if not os.path.exists('users.json'):
    open('users.json', mode='wt').write(json.dumps({}))

authManager = AuthManager(
    # Get your client/tenant ID by following these instructions:
    # https://docs.microsoft.com/en-us/azure/storage/common/storage-auth-aad-app
    microsoftClientID=creds.clientID,
    microsoftTenantID=creds.tenantID,
)

authManager.SaveIncompleteOACallback = lambda ID, data: open('incomplete.json', mode='wt').write(
    json.dumps({ID: data}, indent=2))
authManager.GetIncompleteOACallback = lambda ID: json.loads(open('incomplete.json', mode='rt').read()).get(ID, None)

authManager.SaveToDBCallback = lambda ID, data: open('users.json', mode='wt').write(
    json.dumps({ID: data}, indent=2))
authManager.GetFromDBCallback = lambda ID: json.loads(open('users.json', mode='rt').read()).get(ID, None)

MY_ID = 'Grant'

user = authManager.GetUserByID(MY_ID)
if user is None:
    # the user has not authenticated before
    d = authManager.CreateNewUser(MY_ID)
    webbrowser.open(d['verification_uri'])
    print('Enter the code', d['user_code'])

    while True:
        time.sleep(d['interval'])
        status = authManager.CheckOAStatus(MY_ID)
        print('status=', status)
        if status == 'Success':
            break

    user = authManager.GetUserByID(MY_ID)

print('user=', user)

The output looks like

>>> Enter the code A4S4QS4EG
>>> status= Waiting for user to authenticate
>>> status= Success
>>> user= <User: ID=Grant, EmailAddress=grant@grant-miller.com, AccessToken=abcdefghijklm...>
