I’d like to also see 2FA added, especially if we ever see a web version. That being said, I think there needs to be a fail-safe for it, I recently had to factory reset my phone (there was a whole google-caused issue with Android and i couldn’t fix it, factory reset my phone to sort it, turned out there was a fix 8 hours later), basically i thought I’d backed up my google authenticator to be able to reinstate it when i had my phone sorted, however it didn’t work and I was left locked out of some apps.
Every app/website i had linked to it, had a failsafe in case you lost the authenticator, they were still pretty secure ways to authenticate (given, not as secure as 2FA), but it allowed me to access said accounts again. Unfortunately the only thing i couldn’t get back into, was my Freetrade forum account. (I’m still awaiting a response from someone about un-linking it)
So if it is something that gets added, please at least add another way to regain access/authenticate, even if it involves contacting support and proving you are who you say you are.
