The warning I wish I had (and at least 1 other person ha), sorry my title could be better but I'm a little loopy out of the hospital.
As I'm sure many of you here have 2FA set for Paypal, my choice of authenticating was via SMS OTP, if I was buying on the phone I could literally just press one button to copy and paste, boom done.
As I was placing a lot of orders consecutively one day for a particular pizza chain, I turned off 2FA's just so that I didnt need to authenticate every login. When I went to turn it back on, there was no option to set a SMS 2FA, only Authenticator. Thought it might have just been a 24hour timed thing as I just turned it off but no, a week later still Authenticator only! or some weird key.
Now I mostly make my purchases directly from my Cashback App's in-app browser, I always just complete it right away without minimising the tab since I get mf enraged when they accuse me of 'clicking away, minimising my tabs etc' when I know I didnt. Yet, with Authenticator, I would have to back out, find the App, click the code etc, so much extra steps compared to the good ol' days of clicking 'copy XXXXX' and pasting it in 2 seconds.
Reached out to Paypal to see if it's something they can reapply to my account, and they said no. Once SMS 2FA is turned off, it will no longer be an option further onwards. if they had put that out as a warning before, I would have never turned it off, so I'm annoyed to h3ll. I can still get SMS 2FA by clicking the 'dont have the app' something like that and 3 clicks later will send me a text but hey, now you know!
Paypal's response to my request :
Text message or SMS confirmation for 2FA is already removed and not available for 2FA option. 2FA can only be activated through authenticator app.
You can refer to the Help page of your website regarding 2FA, or simply click this link: https://www.paypal.com/au/cshelp/article/what-is-2-step-veri… for your reference. The article indicates that accounts that has 2FA via text activated will continue to have this feature, but the user cannot re-enable this feature again once turned-off and really need to use the authenticator for 2FA.
SMS 2FA is not secure anyway, it's considered the weakest in the security hierarchy of 2FA methods. Lots of companies are dropping SMS 2FA. https://twitter.com/troyhunt/status/1627068015958454276?lang…
TBF Authenticator isn't bullet proof either (you can be tricked via phishing or social engineering), but at least it can't be defeated via SIM swapping or number jacking attacks.
The most secure method is to have a hardware key, Paypal gave me a freebie years ago after I made a customer complaint, but once the battery ran out, they no longer issued replacements and told me to use another method.
