If you received the "Wells Fargo Restricted Account" message below when you attempted to log into the Wells Fargo app or online banking, it is a glitch, not the result of hacking. It seems the message was sent by accident. 8443576606 is a legitimate Wells Fargo telephone number.
The "Your Accounts have been Restricted" Message
WELLS FARGO
Your accounts have been restricted. In order to regain access and avoid further action on your accounts, please take immediate steps to visit your local branch or call us at 844-357-6606..
Therefore, there should is no need to call the 844 telephone number if you received the message in error. If you have any doubts and think your account may actually be restricted, call the number on the back of your card to confirm everything is okay with your accounts, or go to your local branch.
There is no ETA on when the glitch will be fixed, however if you keep getting the message, you can try logging out and immediately logging back in, as this seems to make the message stop appearing for some customers.
Since this is a "known error," there should be no need to reset your password, however, you can if you want, just to be safe.
