Why people self-host Passbolt
Passbolt is built for teams that need shared credentials, roles, auditability, and a more explicit business workflow around passwords. It is strongest when credential sharing must be governed instead of informal.
The tradeoff is a heavier stack and more process than a household vault usually needs. Plan email delivery, user recovery, and backup verification before rollout.
Deployment notes
Passbolt is listed with support signals for linux, docker. Check the upstream documentation before exposing it to the internet, review authentication defaults, and keep backups outside the primary host.
