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.

    vnEdu LMS mọe đăng nhập thì báo "Tài khoản đã bị khóa", gv chưa hề nói gì về vụ này, acc này từng vào và chạy bth nhưng tầm 1 năm sau vào lại thì nó bắt đăng nhập lại từ đầu (ko cloud sync), đăng nhập đúng acc - pass thì báo acc đã bị khóa, mọe nó ngu quá. Nói thật, khứa nào lập trình viên app này?

Questions about this idea

Is Education: Poor Login & 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?
17 different people described it independently, in 17 mentions, the earliest from 15 Jun 2021 and the most recent from 29 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. 3 people raised it in the last 30 days and 4 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.

    Phần đăng nhập của HOCMAI khiến nhiều người bực mình vì không nhận được OTP và lỗi kết nối liên tục, có đến 13 người đã nhắc đến vấn đề này. Mọi người có ai đã thử liên hệ hỗ trợ chưa, và họ có giải thích gì về việc OTP không gửi về không?
