The Problem
Your next user might arrive through an agent. Your login needs to let it in.
03
The user has to take over.
Instead of finishing the task, the agent sends the user back to a login screen. Some never come back.
Enter Versine
Add Versine to your sign-in page so agents can create accounts and log in for their users.
Keep the auth you already use
Versine integrates with your existing auth provider through a standard OpenID Connect (OIDC) connection.

Don't see your provider? Versine uses OIDC, so any provider, or no provider, can support us. See the integration guide if you need help.
Assistants don’t lack intelligence,
they lack autonomy.
Give them a way through the login screen. Versine lets agents sign in with their user’s permission, so they can get on with what they came to do.
