Setting up 2FA for a vessel computer with Keeper
Keeper works as an Authenticator. Here's how to set it up for a vessel asking for Multi Factor Authentication setup.
Start by going into Keeper. Logins are kept under "Vessel 365 Logins". Make a new record here.

Fill out the login info for the vessel. Afterward, hit Two-Factor Code on the bottom of the Record page. Then hit "Manual Entry > Setup".

Log into the Microsoft app that you're trying to set up (This example is OneDrive for the Petro Mariner barge). When asked to set up an Authenticator, choose "I want to set up a different Authenticator app"

Under the QR code, click "Can't Scan Image?" and copy the Secret Key. Paste that into the 2FA setup page on the Keeper Record. Settings should default to what's shown below.

Afterward, use the new "Two Factor Code" entry on the Keeper Record page and paste that on the next Authenticator screen and any time you need a 2FA for that vessel.
