OAuth (Open Authorization) is the official authorization system provided by Upwork. It allows you to:
Log in through Upwork without sharing your username or password with third parties (like Upsky).
Grant limited access to your account (for example, only for messages - without payment access).
Revoke access at any time through your Upwork account settings.
🛡️ You never share your login credentials with GigRadar CRM.
You confirm access directly on Upwork’s website - the same security standard used by Google, Facebook, and Instagram.
