The error message “SQL Server error 18456: Login failed for user <username>‘” may appear, under certain circumstances, when you attempt to access your SQL Server database using a specified username and password. In this article, we’ll be discussing about how you can resolve the issue.
How to Resolve the “Login Failed for User” Error
This error indicates that something went wrong during the authentication procedure and access has been denied to the user identified by <username>. This error can occur for a few typical reasons. Checking the credentials again is a good idea because they can be the main reason for getting this message.
It might also be the result of the user having insufficient permissions, problems with the authentication mode, or difficulties with login management. You must check the user’s permissions, the credentials, and the configuration of the authentication mechanism in order to resolve this error.
Let’s See an Example
For example, if you try to log in using the username “johnsmith” but receive the error message “SQL Server error 18456: Login failed for user “johnsmith””, you should verify that your login information is accurate and that the “johnsmith” user has the appropriate access rights to the database.
You must look at the authentication setup, user permissions, and supplied credentials in order to fix this error. You can solve the problem and log into the SQL Server database by taking care of these issues.
