even SMS 2FA if I am not mistaken (I receive SMS from them from time to time)
SMS is a very insecure method of 2FA, and if you have an app which is using it, I would suggest either disabling it (if you can) or changing app altogether. It is relatively easy (certainly easier than most other forms of phishing or hacking) for an attack to learn enough about you through social media or similar to phone your mobile company and convince them they are you, and to move your number to a new SIM. Once they do so, they can use that to reset passwords or in this case use 2FA for whatever you have linked.
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, 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.
