Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

NEVER store passwords in plain text.

And why are you re-inventing the wheel? ASP.NET has several perfectly good authentication systems built-in - for example, ASP.NET Identity[^]
