When it stinks, it really stinks

While this app is pretty convenient when it works, the issue is, it never seems to work. It’s frequently not recognizing or verifying your log in info. Locking you out from seeing your account(s). Then you need to call and deal with all that. Who has time?? And don’t get me started on their website UX.

I am not the most ‘tech’ person what so ever but when it comes to Greylocks online banking I feel as though I am pretty tech savvy. The app is that simple to navigate.

Greylock continues to be a loyal banking partner to me as I will to them. If only all things could be this smooth in life. Thank you , Greylock Federal Credit Union.

Worst online banking app

Finger print access is a joke. Constant lockouts even with a password which require a call to IT support to unlock the account access again. Even though I use the same device to log in, I am constantly getting inconvenienced by having the app not recognize my device and requiring a pin to log in, which is sent via text. While security prevents access of my account from others, it also does the same with account holders trying to access their own accounts. This is the worst banking app I’ve ever seen.
