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?
As much as possible don't put all your info in one place. For example, it is better to use a flash drive to store your data since it is much convenient to hide it in a safe place than storing your file on pc, smartphone and tablet where it can easily phished if your security is not that good. Always track your movements, logins and wallets. Always check for token movements in your wallet to prevent any suspicious activity. Do not click unsecured sites and message from spam and unknown sources.
