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?
You don't need to buy a phone for extra security. Whenever you create the 2FA login then Google will always ask you to save private words or paraphrase or will prompt the window to print it. You can always use them to recover all your accounts in case you loose your phone.
Google has already taken care of that thing, they have already thought about the lost phone situation and made extra security about it. May be you have not read the terms properly. Most of the people dont actually.
Yeah.everytime I log in my account Google always asking for saving , me I am still using notebook now and I keep it in my private room, well what ever you use about your private key the most important is you have back up.
