I have ten other savings accounts which use the simple method of sending a code by text. The image scan option is fine if you have 5 minutes to spare while it tries to work. ### 1/5 — Useless system *2025-05-01, version 1.8* Get a new phone, can’t activate app or login online, because you need the app - to login. Can’t access app, because I can’t login. Stuck in a loop. ### 1/5 — Why can’t I give zero star rating *2025-04-14, version 1.8* The authenticator app requires constant re-registration and even when you do that, you still can’t login! I’m literally taking my money to another bank because the Authenticator app is so rubbish. ### 1/5 — Terrible *2025-03-24, version 1.8* This is just a really poor app, performs badly, slow, painful to use and dated. ### 1/5 — Doesn’t work after changing phones *2025-03-10, version 1.8* I’ve tried so hard with this since changing my phone including calling Cynergy. Being sent new passcodes which take hours to receive and then being advised that they will send another new passcode to replace the old/new passcode means more wasted time. I have given up! ### 1/5 — Have to re register the app every time I want to do anything *2025-02-10, version 1.8* Time consuming and flawed ### 1/5 — Useless *2024-12-23, version 1.8* This app is useless. I have to re-register every time I log into my account because the app either crashes or resets itself. It is the most frustrating experience. ### 1/5 — Worst online experience I’ve ever had *2024-10-01, version 1.8* Only giving 1 star as zero is not an option. Have to struggle with authentication every time I login. Essentially impossible to quickly check any of your accounts. First time I have ever reviewed an app. ### 1/5 — Appalling *2024-09-16, version 1.8* Avoid at all costs, put your money elsewhere, the Authenticator is absolutely useless. It never works. I will never bank with Cynergy again because of it. Their security team should all be sacked. ### 2/5 — Doesn't remember app registration *2024-09-03, version 1.8* When I got a new phone I had to re-register this app. Fair enough. However it doesn't remember that it is registered and every time I want to use it, I have to re-register it which is tedious to the extreme. To the extent that it has driven me to seriously consider closing my account and moving it elsewhere. ## Frequently asked questions about Cynergy Bank Authenticator ### What does the Cynergy Bank Authenticator app do?
