The playbook can install and configure [beeper-linkedin](https://github.com/beeper/linkedin) for you, for bridging to [LinkedIn](https://www.linkedin.com/) Messaging. This bridge is based on the mautrix-python framework and can be configured in a similar way to the other mautrix bridges
The bridge automatically performs Double Puppeting if [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) or [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service is configured and enabled on the server for this playbook.
Enabling [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.
Enabling double puppeting by enabling the [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service works at the time of writing, but is deprecated and will stop working in the future.
After successfully enabling bridging, you may wish to [set up Double Puppeting](#set-up-double-puppeting-by-enabling-appservice-double-puppet-or-shared-secret-auth), if you haven't already done so.
If you don't have 2FA enabled and are logging in from a strange IP for the first time, LinkedIn will send an email with a one-time code. You can use this code to authorize the bridge session. In my experience, once the IP is authorized, you will not be asked again.
