Friendly reminder to backup your 2FA

First of all, if you're still using 2FA through SMS, you really should consider switching to an authenticator app such as Google Authenticator or Authy. This is a significantly safer option than receiving 2FA codes via SMS.

Once you've done that, save yourself a potentially MASSIVE headache in the future and backup your 2FA. Ask anyone who has lost their primary device how much of a pain in the ass it was to get their access back to all their crypto accounts and you'll realize why. Most authenticator apps allow you to either enable multiple devices, export a token or generate a QR code to regain access to your 2FAs on another device. This is particularly important if you keep your authenticator app on your primary mobile device, which you're more likely to lose/break than a device that doesn't leave your house.

As an example, I keep a backup of my 2FAs on an old smartphone that I no longer use. It just stays in a safe place in my home and if anything happened to my primary device I'd still be able to access all of my crypto accounts.
