Flaws in deterministic password managers
The only deterministic password manager you need is your own mind. Come up with a set of password rules that are generic enough to accommodate all these issues. For example my deterministic password manager might be:<p>1. random english wordx2 + first 4 letters of registered domain, all caps + remaining lowercase + number of letters in domain (integer) + symbols associated with digits of the integer digits<p>2. If site doesn't allow special characters, remove them<p>3. If site requires a shorter password than the generated one, trim the minimum number of characters from the front of the password until the criteria is met.<p>So, using my above rules my password for Ycombinator would be:<p>coppercopperYCOMbinator11!!<p>If the site restricts passwords to max 12 characters, it would become:<p>Mbinator11!!
