Kaizan uses OAuth to sign you in via your work email. If you sign in with the wrong account — for example, using a personal Google account when your organisation uses Microsoft — you'll see an authentication error.
To reset your authentication and sign in again, go to:
When you sign in, make sure to grant Kaizan access to your calendar and inbox so that meeting and email sync work correctly.
Note: If you're signing in with Microsoft, you'll see two options: Work/work and Personal/work. Select Work/work.
If you're still unable to sign in after resetting, contact support@kaizan.ai.
