You can always manage your integrations in your account settings:

Some services require you to login, while others may require an API key that you can find in their service. There also may be additional info required, such as a domain or workspace name, to ensure you’re connecting to the proper account.

Respell does not current support multiple linked accounts to the same service, but this is on the roadmap!

Note that linked accounts are current linked to a specific user account, not a workspace. When you use an integration in a spell, you are using the account linked to your profile. Your workspace’s members can use spells with your integrations, and the spell will continue to run. However, if they duplicate the spell, they will need to replace their own linked accounts in the integration.
