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?
back up is important because you can rely on it when you needed it the most like in your phone or in comp. you can back up data files etc. so if it accidentally delete you can rely on your back up or sometimes we can use back up in our daily life in our job in studying .for example when your car have flat tire there are always have a reserve tire in case of something happen you have always a back up.
