POS & Retail: Complicated Login and Authentication

Users are experiencing significant difficulties with the login and authentication processes, including frequent login errors, lack of password recovery options, and the need to repeatedly enter passwords. This leads to frustration and a negative user experience, as many users are unable to access the app or are forced to delete it due to these issues.

23 different people have complained about this since 29 Mar 2018, most recently on 22 Oct 2026. 1 of them in the last 30 days.

Is this a startup idea?

Not directly. These are complaints about a product or service people already use — the fix belongs first to that provider.

    KiotViet — Đơn giản hoá quá trình đăng nhập lại và pass Đơn giản hoá quá trình đăng nhập và password đừng yêu cầu rườm rà. Tôi nhiều lúc login vào bán hàng nó đá ra rồi phải làm một mớ việc để đăng nhập cho xong chắc khách bỏ về hết. Đơn giản ngắn gọn. Cho login bằng mã Pin càng tốt. Bấm cho lẹ khỏi xác minh nhìu bước…

Questions about this idea

Is POS & Retail: Complicated Login and Authentication a startup idea?
Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
How many people have this problem?
23 different people described it independently, in 23 mentions, the earliest from 29 Mar 2018 and the most recent from 22 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
Is this problem getting worse?
Status: steady — no change the counts can show. 1 people raised it in the last 30 days and 0 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
