What is the difference between 401 and 403 errors?

Error codes 401 and 403 are often used interchangeably, but in reality, they are completely different.Error 401 means that the credentials you entered are invalid and you’ll have to enter the correct information to log in. It can also mean that the credentials entered by the user are not valid to access that resource.


Error 403, on the other hand, means that the server refused to authorize a user’s credentials because they were insufficient to grant access. Even if the user re-renters the credentials, the result will be the same. The only fix is to request the website owner to grant access to that resource.
