Terminus is nice and has a lot of platform options. Ive used on an old ipad in the past. If you have several machines, I highly recommend servercat. Works wonderfully on iphone, ipad, and Mac. It also has options to write and store commands to easily send out to any number of devices with a taps/clicks.
For what it’s worth, as of a minute ago the form that’s for sending the email code asks if you have reliable access to the email before sending the code.
But otherwise seems to be a non-issue with any of the software/hardware mfa options it supports. Good to let others know about this though!
