This is the original 10 character version of the SS64 password generator. [Security comparison]
Although 10 mixed characters/symbols are just enough to be secure it is likely than within the next few years 10 digits will become crackable in a number of hours, I therefore recommend moving over to the 15 or 20 character versions.
All the major websites now support at least 15 character passwords.
When using a different PC? you can re-generate the same set of passwords at any time by returning to this page and entering the same master password. All the websites get different passwords, but you only have to remember one!
