What this tool is good for
This generator creates random strings using the character sets you choose, including uppercase letters, lowercase letters, digits, and symbols. You can also exclude confusing characters or provide a custom symbol set.
That makes it suitable for passwords, tokens, temporary credentials, invite codes, and general-purpose random strings.
How to use it
- Choose which character groups to include.
- Optionally enable custom symbols or excluded characters.
- Set the target length and the result updates immediately.
- Refresh for a new value and copy it when ready.
Practical notes
- Excluding characters like 0/O or 1/l can reduce mistakes when people need to read or type the value manually.
- Longer output generally provides more entropy than very short strings.
- If a target system limits supported symbols, adjust the custom symbol set before copying the result.
