Working through FTP is very comfortable and fast. This protocol is used to exchange data, files, and folders. This standard is especially popular among webmasters who use FTP clients to download files to the server. But sometimes you get FileZilla "530 login authentication failed" error and you are not able to connect. In this article, we will look at 530 error, which one day your FileZilla client might appear when trying to log in to the host.
What is the reason for the 530 Login authentication failed?
FileZilla 530 Login authentication failed usually occurs when you are using whether an incorrect username, password, hostname, or connection port.
The first thing you need to do is make sure you are using the relevant and correct username and password when accessing the server. If one of those is incorrect - you'll definitely get 530 error, so double-check if you are using the correct credentials. If you are 100% sure that you are using valid credentials - check if the domain is pointed correctly to the server and reset the password.
On the other hand, the problem can be inside FileZilla. Perhaps the login authentication error 530 failed because you have activated an unusual encryption mode in the settings. Maybe during the last session, you've changed the settings for the sake of interest, which eventually results incorrect login 530. Then go to the settings in the "Encryption" section and set "Use simple FTP". And although this is not entirely correct in terms of security, it's better than not accessing the server at all.
If you are using cPanel - there may be two types of FTP accounts: default and additional (pointed to a certain domain). For the default account, the login to FTP is the same as the username. But the additional FTP accounts are in the format «[email protected]», so make sure you are using relevant login details in cPanel.
FTP database corruption
Pure-ftp accounts and users' passwords are stored in an encrypted database. It may be corrupted due to incorrect cPanel updates or inaccurate FTP server changes. Database corruption may cause even bigger problems, than 530 login authentication errors. The fastest way to solve this problem is switching from pure-ftp to pro-ftp and back - this recovers the database with passwords.
And if you are using cPanel / WHM - you can sync the passwords and replace the corrupted database with a relevant one.
When you get "530 Login authentication failed" error - the first thing you should do is to check if you are using relevant credentials. Also check that you didn't copy any extra space or symbol with the password. If you are using relevant credentials, and still get 530 error - try to reset the password. If nothing above does not help - then the problem is in the database and you already know what to do :)
