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: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 digits2. If site doesn't allow special characters, remove them3. 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.So, using my above rules my password for Ycombinator would be:coppercopperYCOMbinator11!!If the site restricts passwords to max 12 characters, it would become:Mbinator11!!
