Don't spread FUD in the beginners section please, 2FA by SMS is not the safest method but it's not a "very insecure method"... SIM jacking is not a massive threat,
Oh it's definitely insecure and
could be a massive threat. Though I'd say SMS auth is better than no auth at all, there's zero reason for a person to not use app 2fas.
beginners shouldn't need to understand and install dozens of app to use bitcoin. Using bitcoin should be an easy way of sending funds, not a new problem to manage.
Dozen apps? You use one authenticator app for literally almost all important accounts you have all over the web, not only crypto-related apps. Also, you're most likely not going to need 2fa if you're using a non-custodial wallet to start with. Unless you're keeping funds on exchanges(which of course you shouldn't do unless you're a daytrader).
Very good find!
I will try it asap.
I allowed myself to translate it into german. Hope that is ok. I obviously linked your thread as a source

Sure! Hope it could help.
