Password Generator Settings Explained

Learn what password length, uppercase, lowercase, numbers, symbols, and readability settings mean before generating a password.

Updated 2026-05-12 7 min read

A password generator is most useful when you understand the settings. Length, symbols, numbers, uppercase letters, lowercase letters, and readability options all change the kind of password you create.

This guide explains those settings in simple English so you can choose safer options for everyday accounts, work tools, Wi-Fi, banking, and accounts you need to type manually.

Password length is the first setting to check

Length usually matters more than clever substitutions. A short password with symbols can still be weak if it is based on a common word, name, year, or keyboard pattern.

For most online accounts, 16 characters is a good starting point. For email, banking, hosting, cloud storage, password managers, and business admin tools, use 20 characters or more when the service allows it.

  • Use 16 or more characters for normal accounts.
  • Use 20 or more characters for high-value accounts.
  • Use a passphrase when you must remember or type the secret often.

Uppercase and lowercase letters

Uppercase and lowercase letters increase variety. They also help meet password rules on many websites. The important part is that the letters are random, not a predictable pattern like Capitalizedword2026.

Keep both uppercase and lowercase enabled unless a website has unusual restrictions.

Numbers and symbols

Numbers and symbols can make a random password stronger and help meet website requirements. They are most helpful when they are random, not when they replace letters in common words.

For example, P@ssw0rd is still weak because the pattern is common. A random password with numbers and symbols is much safer.

  • Enable numbers for most accounts.
  • Enable symbols when the website accepts them.
  • If symbols cause problems, increase the length instead.

Easy-to-read settings

Easy-to-read settings remove characters that are easy to confuse, such as similar-looking letters and numbers. This can be useful when you need to type a password from one device into another.

The trade-off is that removing characters reduces the character pool. You can balance this by using a longer password.

Practical examples

  • Banking account: 20+ characters with uppercase, lowercase, numbers, and symbols.
  • Wi-Fi password: long passphrase if guests need to type it manually.
  • Old website with symbol restrictions: use letters and numbers, then increase length.
  • Device setup screen: use easy-to-read mode to avoid confusing characters.

FAQ

What is the best password generator setting?

For most accounts, use a long random password with uppercase, lowercase, numbers, and symbols. Save it in a trusted password manager.

Are symbols required for a strong password?

Symbols help, but length and randomness matter more. If a site rejects symbols, make the password longer.

Should I use easy-to-read passwords?

Use easy-to-read mode when you must type the password manually. Use extra length to balance the smaller character set.

Conclusion

Good password generator settings depend on the account and how you will use the password. Start with length, enable character variety, and use readability options only when typing accuracy matters.
