Choosing a different password for every account is a good practice. While remembering them is hard, password management systems keep them organized. However, logging into an account from a different computer than yours might be challenging since you have no access to the secrets from there.
Secretstore is filling the gap by providing a web interface to your keyrings.
Currently only Gnome Keyring files are supported. There is a plugin that allows Gnome Keyring integration with Firefox.
