How can I manage assignments between services/tokens and domains?

You can manage the assignment of a domain with a given service in 2FAS Auth. Long-press on the service/token you’d like to edit and choose “Edit”. Go to the “Browser Extension” option. There, you will see a list of domains with which the service/token is paired. You can delete individual assignments, but you can’t modify them.

To add an assignment, send a request for a token to the mobile app from the browser extension level. Then, in the app, choose the correct service with which the domain is to be associated.
