How to move away from Big Tech Two Factor Authentication

Here's a guide on how to easily get away from Google Authenticator and LastPass Authenticator.

Google offers an export functionality for all One Time Passwords. Authenticators listed above can import these items and can be used out of the box. Same goes for exports of LastPass Authenticator. Microsoft Authenticator does not allow export, so migration needs to be done manually by setting up 2FA anew for all accounts affected.
