Still, after years not good enough.

Every day I see “Something went wrong” when I login. Restarting the app sometimes fixes the issues. Also transferring money between accounts takes too many clicks. Design improved and bottom area looks clean but top area under account is still yak. There are arrows, horizontal and vertical lines and 3 dots. This is nightmare from a design perspective! Also the rubber band effect is not implemented across the whole app! I also have the ASB app and they got it really clean and intuitive.

App is pretty good. Unintuitive to enable quick login

There’s another comment in a previous reply from the developer which was a game-changer for me. I had no idea why I was having to manually enter my login details so often suddenly; turns out there’s a setting to enable biometric (Face ID etc) login... but that’s seemingly (and inexplicably) only accessible while logged out. Luckily, I’m basically always logged out, I guess. The login/log out process is the biggest headache with this app. Even once I found out how to enable Face ID to auto login, returning to the app after a few minutes logs you out and you have no way of triggering Face ID to re login; you need to key in that big old password to get in again. Ironically, if you choose to retrieve the password stored by Apple in your keychain... Apple then prompt you for your Face ID. The solution in this case is to hard close the app and re-open it, which then automatically checks your face and instantly logs you in. This is all a big distraction from the fact the app itself is slick, really well designed, and clearly has had a lot of thought put into it. I guess there’s some banking regulations at play here that are not customer friendly for login, and that ends up spoiling the experience overall. If it weren’t for login hassles I’d mark this a 4 or 5 star.

Westpac one app is fantastic, however I recently purchased the iPhone X and initially I could use the Face Identification to login, now however it doesn’t seem possible. Personally I believe the developers need to bring this back to the app. As with touch I.D. The convenience was next to none. It’s like taking a step back to the Stone Age with not being able to login with either touch I.D. or face I.D. Yet I have apples latest & greatest device. Please look into this Westpac R & D team!!!

Apologies for the significant delay in this.
Face ID is now available on the latest version of Westpac One. Please update to the latest version, then enable it through settings in the ... (more) menu while logged out.
