Description of the enhancement request

Introduce a feature that allows users to change their own passwords, with the option to enable or disable this functionality through settings. This will provide flexibility in cases where a fixed password is required, while allowing or prohibiting individual password changes when necessary.

The goal you want to achieve

The goal is to allow users to securely and conveniently manage their own passwords, while the jury can configure in the settings whether the default behavior is to allow all users to change their own passwords. It should also be possible to restrict certain users from changing their passwords individually.

Expected behaviour

Users should be able to change their passwords via their personal settings page. Administrators should be able to enable or disable password changes for users through system settings.

Any other information that you want to share?

DOMjudge is often used in courses on programming, data structures, and algorithms. In these contexts, student IDs or fixed passwords are typically used for long-term login throughout the semester. However, due to the recent feature in DOMjudge that allows downloading submission code, there have been incidents where some students log into others' accounts to secretly download the correct code. Given the large number of students in such classes, handling password changes individually becomes difficult. Therefore, allowing users to change their own passwords could help mitigate such issues while reducing the burden on administrators.
