I am using 2fa as my security in my emails and exchange accounts, so one day I nearly lost my phone and that phone holds majority of my pins, 2fa, etc. so I thought I lost all, luckily I found the phone. So now I'm thinking of buying an extra phone for backup. What else do you recommend for backup?
Now you realized that negligence will lead to disaster especially to our precious accounts. Even with back-up, if you are too complacent about you accounts the there would be the possibility that you will still loose it.
