In the .htaccess (which is in the root of your website) you can change the max file size.

https://github.com/Elgg/Elgg/blob/7ea56c6dfebd0937c854a92fc12f37b9b19c6c4c/install/config/htaccess.dist#L48-L51

Make sure you also increase the 'post_max_size' to be above the 'upload_max_filesize' because the file size also counts in the post size and the rest of a form also needs to be send in the post size. A safe bet is 2MB more in post size.

Probable this URL could help you http://learn.elgg.org/en/stable/design/security.html and while you are in the administrator panel, maybe you could create a second administrator user with different password just in case you ever lose the first admin..

Thanks for the response. This page doesn't list out my exact issue. Also, the example I mentioned above, that a user is facing this, they are already a second admin. But still, when they logout, they are not able to login again with same password. They had to reset password and login every time.

Is there any config on the backend needs to be changed? Or is there a setting in Elgg website to change?

there is nothing in Elgg which does this. In default Elgg the only way a password changes is if the user requested a new password (and clicks the confirm link), if the user changes the password on their settings page or if an admin resets their password (which then send the new password in an e-mail to the user).

There is no mechanism which changes your password on login or logout.

Do you have any 3rd party plugins enabled which could influence this behavior? Maybe a one-time-use password plugin?

It's nonsense to run Debian 12 on a 32-bit platform.

Of course, you should use only a 64-bit platform.

Updated: But you can anyway. Most likely one of the packages requires a 64-bit platform
