FTP is a method for moving files between computers over the internet

FTP stands for File Transfer Protocol. It is a set of rules that lets you send files from one computer to another across the internet. Think of it like a postal system for digital files — you address where the file should go, and FTP handles getting it there.

You do not need to understand how FTP works technically to use it. What matters is recognizing when you are using it and knowing the basic safety concerns. FTP shows up most often when you are uploading files to a website, downloading large files from a server, or backing up data to a remote location.

The reason FTP still exists after decades is straightforward: it does one job reliably. It moves files. It does not do much else, and it does not pretend to. That simplicity is also why it has security gaps that matter for certain situations.

Key Takeaways

  • FTP is a tool for transferring files between computers; you use it when uploading to a website, downloading from a server, or backing up files remotely.
  • Standard FTP sends your login information unencrypted, which means someone on the same network could potentially see your username and password.
  • SFTP and FTPS are encrypted versions of FTP that protect your login details and files during transfer; most hosting providers now offer one of these instead of plain FTP.
  • You access FTP through software called an FTP client, which you read and install, or sometimes through a web browser interface provided by your hosting company.
  • If you are uploading sensitive files or using FTP on public WiFi, encrypted versions like SFTP are worth the small extra effort to set up.

When you actually use FTP in daily life

Most people encounter FTP when they own a website or need to move large files to a server. If you have a website hosted by a company like GoDaddy, Bluehost, or Namecheap, you use FTP to upload your website files, images, and content to their servers. Without FTP, you would have no way to get your files from your computer to the web.

You might also use FTP if you work with a team that shares large video files, design files, or databases. Instead of emailing a 500 MB file (which most email services reject), you upload it to an FTP server and send your coworker a link or login details.

Some backup services use FTP in the background to move your files to remote storage. You do not see FTP happening — the backup software handles it — but FTP is what moves the data.

The security difference between FTP, SFTP, and FTPS

Plain FTP has one major weakness: it does not encrypt your login information. When you enter your username and password into an FTP client, that information travels across the internet in plain text. If someone is monitoring your network traffic — on public WiFi, for example — they could see your credentials.

SFTP (SSH File Transfer Protocol) and FTPS (FTP find) both solve this problem by encrypting everything: your login details, your files, and the entire connection. The difference between them is technical and does not matter for most users. What matters is that both are encrypted, and both are much safer than plain FTP.

Most hosting companies now offer SFTP or FTPS by default and discourage plain FTP. If your hosting provider still offers only plain FTP, that is a sign they are not keeping up with security standards. You can ask them to enable SFTP or FTPS, and most will do it without extra cost.

How to access FTP and what software you need

To use FTP, you need three things: login credentials (username and password), the server address (a domain or IP address), and an FTP client — the software that does the actual transfer.

Popular FTP clients include FileZilla (free and available for Windows, Mac, and Linux), Cyberduck (free for Mac), and WinSCP (free for Windows). You read and install one of these, enter your server details, and you can then browse and upload files as if you were using a file manager on your own computer.

Some hosting companies provide an FTP interface built into their control panel — you do not need to read anything. You log into your hosting account, click a button, and upload files directly in your web browser. This is simpler but usually slower for large files or many files at once.

What can go wrong and how to protect yourself

The main risk with plain FTP is that your password can be intercepted on public networks. If you are uploading files from a coffee shop WiFi, someone else on that network could potentially capture your login details. This is why using SFTP or FTPS matters most when you are on public WiFi or uploading sensitive information.

A second risk is leaving FTP credentials in plain sight. If you write your FTP password in a document on your desktop or share it in an unencrypted email, anyone with access to your computer or email account can use those credentials. Store FTP passwords in a password manager like Bitwarden or 1Password, the same way you would store banking passwords.

A third risk is using the same FTP password for multiple services. If one hosting company is breached and your password leaks, someone could try that password on your other accounts. Use a unique password for each FTP server you access.

FTP versus cloud storage and modern alternatives

FTP is old technology, and for many tasks, cloud storage services like Google Drive, Dropbox, or OneDrive are simpler and safer. If you are sharing files with a team, cloud storage handles permissions, version history, and access control without needing to manage FTP credentials.

However, FTP is still the standard for website hosting and for moving large amounts of data to remote servers. Cloud storage can be slow or expensive for gigabytes of files. FTP is also more reliable for automated backups — you can schedule a backup script to run FTP transfers without human intervention.

The choice between FTP and cloud storage depends on what you are doing. For casual file sharing, cloud storage is easier. For website management or large-scale data transfer, FTP is still the practical choice — just use the encrypted version.

Frequently Asked Questions

Is FTP safe to use on public WiFi?

Plain FTP is not safe on public WiFi because your password travels unencrypted. SFTP and FTPS are safe because they encrypt everything. If your hosting provider offers SFTP or FTPS, use that instead of plain FTP, especially on public networks.

Do I need to know how FTP works to use it?

No. You only need to know where to enter your login details and how to navigate folders in your FTP client. The software handles the technical details. If you can use a file manager on your computer, you can use FTP.

What if I forget my FTP password?

Contact your hosting provider. They can reset your FTP password through your account control panel. You will not be able to reset it yourself through the FTP client — you have to go through your hosting company's website.

Can I use FTP on my phone?

Yes, but it is awkward. Apps like FTP Disk (Android) and FTP Disk Pro (iOS) exist, but they are clunky for regular use. Most people use FTP from a computer. If you need to move files on your phone, cloud storage apps are usually easier.

Why do some people still use FTP if it is old?

Because it works reliably for its one job — moving files — and it is built into almost every web hosting service. Switching to something newer would require hosting companies to rebuild their infrastructure. FTP is not going anywhere soon.
