What this tool does

Password Strength Analyzer. It creates or inspects security and network values such as passwords, tokens, hashes, authentication data, IP ranges or browser details, as indicated by the title.

When to use it

Use it to learn how length and character variety affect an example password. The estimate is not a security guarantee.

How to use

  1. Enter the value to inspect, or leave the input empty if this tool generates a new value.
  2. Choose the algorithm, mode, length, range or other settings shown by the tool.
  3. Run the check or generation and read any validation message before using the result.
  4. Copy the result if needed. Treat passwords, keys, tokens and authentication headers as confidential.

Tool-specific tip: Enter a sample password to see a local strength estimate and suggestions; avoid entering a password currently in use.
