How to Use a Passphrase Password Generator

Most secure password generators follow the same principles of using random seed values to generate hard-to-crack passphrases and passwords. In addition, all of them will invariably offer options to use or exclude special characters, punctuation marks, symbols, numbers, and letters (uppercase and lowercase.) Here's how most of them work:

• 1. Go to the corresponding website of the password generator (if you sign up for a password manager like 1Password, it's also included in the package.)
• 2. The first step is to tweak the parameters available, which could be character and symbol options, readability, and so on.
• 3. Set the number of characters you want your secure password or secure passphrase to have.
• 4. Click on the button that says “Generate Password” or something similar.
• 5. Copy the password using the button or Copy icon, if available, or just do a Ctrl+C/Cmd+C to copy it to your clipboard.
• 6. Paste it into the required application or website.
• 7. Make sure you write it down or remember it so you can recover your account in case you forget the password, which is quite likely if it's totally random.
