Sql for storing users logins and passwords

To add to what Wendelius says, you don't need SQL to implement a secure login ... SQL is all about storing data and there are many different ways to do that, of which SQL allows access to several but by no means all.

The first thing to note is that SQL and MySQL are not synonymous: MySQL is a specific multiuser database system while SQL is a (mostly) generic language for querying data sources. SQL can be used to access a MySQL database, but it can also be used to access Access, Excel, SQL Server, SqLite, Oracle, and many others; and to do other things which indirectly access stored information such as report generation (Crystal Reports, SSRS, ...)

You should not use the two terms as if they are interchangeable!

In fact, many online systems use an Access DB to store login information, though I prefer SQL Server, simply because my hosting service provides it and I see no need to add extra services.

But ... I really wouldn't suggest learning this stuff by creating an online login system, simply because it would be covered by GDPR legislation, and if you don't know what you are doing you could end up in a lot of trouble - it's not a good area for "playing" :laugh:

Instead, why not try setting up a DB to organise your MP3 or MP4 collection? That'll give you a good deal of experience, without any legal ramification, other than if any of it nis pirated and that one is down to you already! LOL.

Yes,
Of course Mysql can do this task.
Just need some code to do the job.
