...if you are willing to sacrifice the "phone" part of it.
It works fine for me.
Fine if you don't need to use it for online banking on your phone, that's my main blocker.
I choose banks which do not require mobile banking, including virtual credit cards. You can also try Waydroid to run Android apps. I heard it worked for some banks.
My bank sends an SMS for OTP.
I know it isn't very secure. But certainly better than having a seed locally stored.
I'd rather a seed on a device I own rather than being able to be smished.
I wouldn't call an Android device "a device you own".
Why don't I own it, explain.
If I can't see the seed and I have no way of exporting it. What do I have?
If I can't see the person in the telco being paid off to have my IMEI reattached arbitrarily, what do I have? A person who can MITM the SMS codes.
