Essentially, I'm just looking to register a phone number and then have 6 digit codes SMS'd to me when required.
But looking at the 2FA options, it seems most require an account to be made with another company or to actually have an app on your phone at all times. Soooo..... yeah...... anyone know which I should use to fit my simple requirements?
I have both 🙂 The only downside with LP is you can't choose which to use if you have multiple registered. Which is a no-brainer really (esp. if you have a authenticator app and a Yubikey and forget one).
SMS is horribly insecure, and I wish companies would stop using it. For authenticator codes, I have switched from Google Authenticator to Authy, which allows me to use more than one device and backs up the codes. For LastPass itself I use Duo Security. I have tried LastPass Authenticator but it never worked right for me so I dropped it.
