Random string and password generator

This tool generates strings with random characters. This is useful eg. when choosing passwords. You can choose uppercase, lowercase, and special characters, as well as change the length of the string.


Number of characters: <-- max. 50, use 0 for random

Use numbers as well as text
Use uppercase as well as lowercase
Use "-" and "_"
Use extra special characters (*)


(*) The extra special characters are: ! @ # % ^ & * ( ) + = { } | ] ? [ : > < , .

Privacy: This tool does not record any information about the strings you choose to generate, the options you choose, your IP address, browser, time of use, frequency of use, or anything else.

Security: This tool contains a PRNG. It is not a CSPRNG. If you know the difference you may think that this matters. It does not: this is not an encryption service, it is a string generator. The tool can be trusted to generate short strings of characters. That, is what it does.
