Random String Generator: Tokens in Exactly the Length You Need
Codes, tokens, and temporary keys all need precise lengths and character sets. This generator gives you both.
What is the Random String Generator?
Random String Generator builds a string exactly as long as you ask, using only the character groups you select. Mix lowercase, uppercase, digits, and symbols for tokens and temporary codes, or keep to letters and digits for friendlier codes. Checking the length and character set of the result takes the guesswork out of whether the string matches your requirements.
How to use it
- Set the length you need.
- Tick the character sets to include.
- Press Generate String and copy the result.
Worked example
Generate a 16-character string from letters and digits and the tool reports its length and charset compliance.
How do you check a random string?
Confirm its length matches what you asked for and that every character comes from the sets you selected.
Frequently asked questions
Can I use this for passwords?
It works for temporary codes and tokens, but a password manager is safer for accounts you keep.
What if I select no character sets?
The tool will ask you to pick at least one set before it generates anything.
