The Account Settings page, accessible via the user icon at the bottom of the sidebar, is where you manage your personal profile and technical integrations.
Under the General tab, you can keep your profile up to date:

The API Key tab is the gateway for developers who want to move beyond the dashboard and integrate Provably’s proof-generation capabilities directly into their own systems.

Using your API Key
Your API key enables your systems to securely call Provably services and authenticate your requests programmatically.

WARNING [Protect your Key] When you generate a new API key, save it immediately in a secure location. For security reasons, you will not be able to view or recover it again once you close the notification. If lost, you will need to generate a new one, which will invalidate the previous key.
