The most commonly used passwords are alphanumeric, including both upper and lower case letters, on most systems. Most systems limit the length of passwords to 8 characters, but there are cases of legal passwords with many more than that as needed. There are instances where some very high security systems include spaces (the character generated by the space bar) in a password. We are not using spaces in the generation of passwords and we do NOT suggest using spaces. To clear the entries in the created password box click on Clear Values.
