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?
I recommend you to write down all the private information of yours and put it in the safest place you think no one can find out. Don't just put all personal and private informations in 1 gadget only. Make sure your money is not in one place only. You should divide it and place in different wallet. And the last thing is make sure you protect it in all cost.
