What is leet speak transformation?

Leet speak replaces letters with similar-looking numbers or symbols. For example: 'a' → '4', 'e' → '3', 'i' → '1', 'o' → '0'. Our advanced mode offers multiple substitution options for each character, increasing entropy.

What is the best transformation strategy?

Domain-specific for unique per-site passwords, or leet speak (advanced) for general strengthening. Use preview grid to compare all options.

What is the reverse transformation feature?

Reverse transformation attempts to decode leet speak passwords back to their original text. This is useful for understanding what phrase was used or for educational purposes. It works best with basic leet transformations.

How do custom leet maps work?

Custom leet maps let you define your own character substitutions beyond the standard leet speak alphabet. You can save these presets locally and reuse them. This creates personalized transformations that are harder to guess.

How do I save my custom leet mappings?

Switch to Custom Leet mode, define your character substitutions, then click "Save Preset" to store them locally in your browser.

What is Password Transformation?

Password transformation converts memorable base passwords into stronger variants using character substitution, case changes, and pattern modifications. This helps create passwords that are both secure and easier to remember than completely random strings.

Memory Aid: Start with memorable phrase or word
Strength Boost: Transform into more complex password
Multiple Variants: Generate different versions from same base
Leet Speak: Replace letters with numbers and symbols
Secure: Transformations happen entirely in your browser

Transformation Methods

Leet Speak: Replace letters with similar-looking numbers/symbols (e → 3, a → @)
Case Alternation: Vary uppercase and lowercase letters
Prefix/Suffix: Add numbers or symbols to beginning/end
Character Doubling: Repeat certain characters for length
Reversal: Reverse parts or all of the password
