Good day, just want to share my experience,
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?
That's a lesson learned for you that don't just put everything on a single phone, recovery phrases, seeds, private keys and of the same must be backed up.
Having an extra phone is a good idea and you can leave the other one at your home while bringing the other one.
Writing up those important words on a piece of paper is an easy, simple and cheap way of backing up.
