Currently looking into setting up a lockdown device for 2factor, and possibly cold storage for passwords and things.
What would be the best route to do this?
What are your fave auth apps?
Would saving this stuff on a specific machine work?
Laptop or a phone?
I will later probably buy a yubikey and not think about this sorta stuff ever again, but atm I have a netbook that could work for this, an android 2.2.3 phone doing nothing, and another phone that I am going to make into a wallet storage box, for the most part that runs android 7. Technically 2 that run 7, but the other one runs a russian rom and I don’t trust it with much more than my podcast player.
Thanks for any recommendations.
