WebSecurity - Login()

❮ WebSecurity


The Login() method logs in a specified user, using a username and a password.

C# and VB Syntax

WebSecurity.Login(userName, password, persistCookie)


Example C#

if (WebSecurity.Login(username,password))
<p>Incorrect username or password.</p>

Example VB

if WebSecurity.Login(username,password)
<p>Incorrect username or password</p>
end if


Parameter Type Description
userName String The user name
password String The user password
persistCookie String true to specify that the authentication token in the cookie should be persisted beyond the current session; otherwise false. Default is false.

Return Value

Type Description
Boolean true if the user is logged in, otherwise false


When a user is logged in, ASP.NET sets an authentication token in a cookie that lets ASP.NET know on subsequent requests that the user has been logged in. If persistCookie is false, the token is valid only until the user closes the browser.
