The Hidden Risk of Standard Email Attachments
Most of us use email every day without a second thought. However, sending a standard attachment is a bit like sending a postcard through the mail—anyone who handles it along the way could potentially read the contents.
If you are sending a passport scan, a tax return, or a legal contract, “standard” email isn’t enough. To keep your data private, you need to lock the file before it ever leaves your computer.
Step 1: Use Client-Side Encryption
The most secure way to protect a file is to encrypt it locally. Using a tool like SecureAnyDoc allows you to apply AES-256 bit encryption—the same standard used by banks and governments—directly in your browser.
- Why Client-Side? This ensures the unencrypted version of your file never touches a server. Only the “locked” version is handled.
Step 2: Choose a Strong, Unique Password
Your encryption is only as strong as your password. Avoid common words or birthdays. Instead, use a mix of uppercase letters, numbers, and symbols.
Pro Tip: Check out our guide on how to create an unbreakable password for your encrypted files to ensure your data stays truly private.
Step 3: Send the File and Password Separately
This is the most important rule of digital hygiene: Never send the password in the same email as the encrypted file. If a hacker gains access to your email account, they will have both the “lock” and the “key.” Instead, share the password via:
- A secure text message (SMS).
- A phone call.
- An end-to-end encrypted messaging app.
Why You Should Never Send Unencrypted IDs
Cybercriminals often target email accounts specifically to find “identity sets”—combinations of IDs and utility bills that allow them to commit identity theft. By taking thirty seconds to secure your documents, you eliminate this risk entirely.
