Bitwarden is a free and open-source password management (password manager) service that stores sensitive information such as website credentials in an encrypted vault. The Bitwarden platform offers a variety of client applications including a web interface, desktop applications, browser extensions, mobile apps, and a CLI. In this step by step guide I will teach you how to install official Bitwarden on your Synology NAS device using Docker & Portainer. Note: If you want to Install Vaultwarden instead of Bitwarden, check out my articles on How to Install Vaultwarden on Your Synology NAS and Install Vaultwarden With Portainer. Note: If you like, you can use Passbolt as an alternative to Bitwarden.

💡Note: This guide works perfectly with the latest Bitwarden v2023.9.0 release.

Warning: This is a beta release.

Your official Bitwarden at a glance!

• STEP 29

One of the most important things you need to know about Bitwarden is that anyone who can access your HTTPS Bitwarden link can register for a new account by default. Follow my step by step guide below to disable registration of new users in Bitwarden. Open Portainer then go to stack. Localize then click on your bitwarden stack that you have previously created at STEP 17. Click the EDITOR tab then change the value on line globalsettings__disableUserRegistration from:

– globalsettings__disableUserRegistration=false to – globalsettings__disableUserRegistration=true

Click Update the stack. Follow the instructions in the image below.

When new users try to register, they will receive the following error message: “An error has occurred. Open Registration has been disabled by the system administrator”. To reactivate user registration, change the value from true to false.

• STEP 30

If you want, you can also access your Bitwarden admin dashboard at https://bitwarden.yourname.synology.me/admin In my case it’s https://bitwarden.mariushosting.synology.me/admin
