This project creates encrypted backups for Bitwarden vaults including attachments. It pulls your vault items from Bitwarden CLI and download all the attachments associated with those items to a temporary backup folder. Then, portwarden zip that folder, encrypt it with a passphrase, and delete the temporary folder.

It addresses this issue in the community forum, but hopefully Bitwarden will come up with official solutions soon.

3/28/20 Update

We now support restoring the backup to an empty account, including attachments.


Note that you may lose your data if you try the restore feature and I am not responsible. Use the free software at your own discretion. Since we don't handle restoration conflicts, make sure to back up with your main account and restore to a spare/alternative account.

Usage Of Portwarden CLI

Go to to download the latest version of Bitwarden CLI and place the executable bw/bw.exe in your PATH. Then, go to to download the latest release of portwarden. Now just follow these steps :

# If you are running self hosted instance, execute `bw config server https://MYSERVER.COM`
portwarden --passphrase 1234 --filename backup.portwarden encrypt
portwarden --passphrase 1234 --filename backup.portwarden decrypt

# Please use a **spare** account for restoring backup
# Portwarden doesn't handle conflicts therefore a
# separate account is needed

# In fact we setup a check to make sure the account your
# are restoring to does not have any data in it
portwarden --passphrase 1234 --filename backup.portwarden restore

Contribution & Development

Clone this repo. Make sure you have Docker installed, ports 8000, 8081, 5000 unused, Golang installed, dep installed. In addition, create an environment varialble Salt of length 30 for encryption salt. Then run

dep ensure           # Install go dependencies
docker-compose up -d # Spin up required containers

# After the services/containers are created successfully, you should see
# $ docker-compose up  -d
# WARNING: Some services (worker) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

Notice the docker-compose.yaml file defines the services running and it's mounting your current directory as volumes and map it to the container's working directory. This means you can develop/make changes in your local machine, and run it in the container. It also maps certain containers' ports into your host so that you can call the endpoints.

PRs are welcome. For ideas, you could probably add a progress bar to the CLI.
