This app is alright. It randomly signs out for no reason and changing devices is a pain. My favorite is when you're trying to sign into a phone app, like Synology Photos, and the approval window appears over the number you need to match it with. So if you can't remember that number you have to back out and look at it again. A minor annoyance.

Works fairly well as far as a rapid two-factor authentication app. The pop-up coordination with the 6 character verify operates a little sludgy. The pop-up for sign in approval that shows up on top of the character display seems to be inconsistent on my phone.

Please name this app the same as it is listed in the Play store, so it is easier to search for in-app lists. "Secure Signin" is too generic. Please change to "Synology Secure Signin"

It works. Just not the smoothest experience. Numbers in circles for sign in requests are oversized, they don't fit in the circles

Incredibly difficult to add a new account, going round in circles and in a chicken-and-egg situation. Had to request an emergency code via email. Even now that my account for my NAS has been added, it just says that I've approved a login successfully but then doesn't log me into the device. Been trying for over an hour now to log into my NAS that I can see and touch but can't log into. Thinking of going back to a QNAP...

Signing into the app requires a code from the app no matter what I do. Password, still requires code. SMS, still requires code. Obviously I can't put in a code whilst I'm trying to sign in. Having had to reset my phone I have now lost access to this.

Thanks to this complete trash app I am now locked out of my server with no way to get back in. + thanks synology for taking my freedom to log in to my server the way I want. It's not like people only buy your products to have some freedom over their choices in the first place.
