I believe some password managers have hard-coded field recognition for popular websites in order to make them work.

For this reason, Firefox’s password manager complements its heuristics with a recipe system, where users can describe specific instructions for specific hosts. Yet, they sometimes still fail to recognise them. Password managers come with all sorts of heuristics to detect username and password fields. Ideally, password managers work in both of these cases: on first time visit (when they offer to store credentials) and on recurring visits (when they let you use stored credentials).ġPassword recognises it has a pair of credentials for this site Things like password generation, offering to save credentials for a host name and filling in the password for you in a secure way.

With ‘playing ball’ in this post, I mean that password managers recognise your login form and let you use their features on your fields. If you’re building a login form, these are some tips to improve the experience for password manager users.

Hence the popularity of password managers. Therefore, remembering them all is impossible for most human beings.
