Revoking Access
Teleport's approach to using short-lived certificates for all infrastructure access means that it can generate large numbers of certificates every day. For this reason, Teleport does not support traditional certificate revocation.
There are two options available for revoking access: CA rotations and Teleport locks.
CA rotations
To generate a new certificate authority and invalidate user certificates issued
by the current CA, run tctl auth rotate --type=user
. This process will require
that the newly generated CA certificate is uploaded to your entire fleet of
OpenSSH servers. This can be a disruptive change, especially in environments
that lack automation, so proceed with caution.
See the CA rotations guide for more details on how to execute the procedure.
Locks
Teleport locks allow you to permanently or temporarily revoke access to a number of different "targets". Supported lock targets include: specific users, roles, servers, desktops, or MFA devices. After you create a lock, all existing sessions where the lock applies are terminated and new sessions are rejected while the lock remains in force.
