The Credentials page serves as a centralized hub for viewing and managing all third-party integrations with Keyflow. ## Integration Methods There are two ways a service can be integrated to Keyflow. ### OAuth 2.0 OAuth 2.0 is a secure and widely-used method for integrating third-party services with applications including Keyflow. Click `Connect` to authorize and connect to any available connections. ### API Key While most third-party services are authenticated via OAuth2 for secure and streamlined access, some may require manual entry of credentials. For services like Perplexity, users are prompted to input their API key for billing purposes. Click on the `Add API Key` to integrate the service with keyflow. ## Revoke Credentials Your control over your data and how it's accessed is paramount. Should you need to revoke Keyflow's access to any service, navigate to the Credentials page, and click **Revoke** button next to the service you wish to disconnect. This action will remove Keyflow's access and all traces of your credentials immediately. All flows relying on these credentials will cease to function until reauthorized. ## Security All credentials are encrypted at rest and securely stored in cloud. Decryption only occurs in the servers during flow execution. ## Available Integrations Here is the list of all supported integrations with Keyflow --
