The amount of services offering (or even demanding) two-factor authentication (2FA) is ever-increasing. This has encouraged me to find a more resilient strategy for how I store, manage, and backup my secret keys. My old approach relied solely on using time-based one-time password (TOTP) applications capable of exporting and importing 2FA accounts.

I recently learned that it’s possible to use Google Authenticator (or any other authenticator app) with Office 365 for 2-step verification. That’s great as I’ve always believed it was Microsoft Authenticator or the highway. I’m sure Microsoft Authenticator works fine, but I don’t want multiple authenticator apps on my phone.
