It is until you end up having to blacklist zelle because your banking information was used to defraud someone. I actually had my account broken into, funds deposited from zelle and then all available funds removed from my account in the space of about an hour. Went to pay for something the day after and had to call my bank’s fraud department. They tried the same thing with a second account of mine but it was flagged immediately when they tried to use the same login credentials (they weren’t remotely the same). So no zelle for me. It’s permanently disabled by both my banks for security reasons.
