Security tip!

Make sure you have a backup copy of your 2FA!

During a "hard reset" of your phone, you will lose all your data, if you do not have a backup copy of the 🔑 2FA key, you will have a challenge to log in to the exchange! The only option is to deactivate this protection by contacting the exchange and usually re-verifying. I use the Authy application for 2FA, where the codes are secured with 2 passwords and in the event of losing the phone or resetting it, you can restore them.

I am reading it now, because I somehow missed it. I don't know if you knew, but authy had a hack and sometimes it stops working, they wrapped phone numbers - it's worth making a copy of 2FA if you don't have it or where you're not sure you have it, you can deactivate and reactivate this protection, it may be worth doing it in 2 places also in the google authenticator application
