I own a handy asus x00p with android 8 that fits my hand (released in 2018). I have a newer android 11 device (released in 2020) but it’s larger and heavier and I don’t really like using it.
What are the security risks, if I go ahead using the 2018 model to 2fauthenticate?
None if you keep it offline
I’m gonna have to ask you to elaborate:
how can I keep it offline? I need to keep the device online to receive the code, right?
