2 Factor security is our best current method of securing our important accounts, having a password is not enough for sensitive items, like bank accounts, personal notes, and other private data.
There are many options to choose from when selecting your two factor authentication app, Authy, Google Authenticator, Microsft Authenticator, LastPass and others.
Our recommended service is Authy.
From the fact that it’s made by a company with a reputation for security, reliability and privacy, Twilio. To the fact that it’s beautifully designed, can (optionally) operate on multiple devices, and keep (encrypted) backups of your two factor accounts in their secure cloud.
Authy wins, in most cases.
