I thought about using pwgen locally with a combination of domain, username and password as a hashed seed. But like you mentioned, trying to remember how often i had to change the password (or had restrictions applied only at a particular site, which are pretty ridicules sometimes) makes this not really a worthwhile solution. Albeit this, its not completely useless. If you have specific rules how to create new passwords (a counter for example) and to circumvent specific restrictions, one could iterate through the possibilities rather quickly. One thing that's unbeatable about this solution is that no password store is needed and so none could be lost, which drove my initial thought to this.
