Holy ...shit.
I have Brave and had started to set up the wallet part but then stopped because I had signed up with my new name (Phoenix), which isn't legal yet, so I decided I'd just let it build up and wait until it WAS legal and then I'd set up the account.
Biometric data?? What the actual fuck? Nevermind, won't be doing that then...
I guess I'll just tip out the BAT I've earned so far to others who may have already done all that. Now I'm super curious whose biometrics are stored as regards corporate entities who are signed up to receive BAT like Steemit, and The Guardian news site. Did Ned give them his retina scan? O.o
