Vaultwarden 1.37.5 on Ubuntu 24.04 with HTTPS, sign-ups disabled and a generated, hashed admin token. A self-hosted, Bitwarden-compatible password manager: invite yourself from the admin panel and register.
This AMI runs Vaultwarden, an open-source server implementation of the Bitwarden API written in Rust, on Ubuntu 24.04 LTS. The container image is pinned to Vaultwarden 1.37.5 and baked into the AMI, so first start does not depend on a registry. Vaultwarden is an independent project and is not affiliated with or endorsed by Bitwarden.
Why Vaultwarden?
Vaultwarden lets you keep your team's passwords and secrets on a server you control and use them from the Bitwarden browser extensions, desktop and mobile apps, which can be pointed at your own server URL.
What Perimattic adds
Pinned, tested version: the image is fixed to 1.37.5, not 'latest', so a rebuild never changes the server behind your back.
Closed by default: sign-ups are disabled, so nobody can create an account on their own. During first-login setup a random 24-character admin token is generated on your server and only its Argon2id hash is stored in the configuration. You log in to the admin panel with that token and invite your own email address; no email server is needed. There are no default or shared credentials in the image.
HTTPS: Vaultwarden needs HTTPS to work in the browser. Apache is configured as a reverse proxy (including WebSocket notifications) and a free Let's Encrypt certificate is requested for your domain with certbot.
Patched base: Ubuntu 24.04 LTS built through an automated EC2 Image Builder pipeline, with security updates applied at build time.
Getting Started
Launch the AMI and open ports 22, 80 and 443 in the security group
SSH in and answer the setup prompts (domain and admin email)
Open https://your-domain/admin and log in with the admin token printed at the end of setup (also in /opt/app/access.txt)
Under Users, choose Invite User and enter your own email address
Open https://your-domain, choose Create account, use that email address and choose your master password
Your master password is chosen by you in the browser, is never stored on the server and cannot be recovered; keep it safe. A domain name with an A record pointing at the instance is required.
This AMI is built and supported by Perimattic. Vaultwarden is an open-source project (AGPL-3.0 licence); Perimattic is not affiliated with its authors.

Highlights
Vaultwarden 1.37.5 pinned and pre-installed: a self-hosted server for the Bitwarden clients (independent project, not affiliated with Bitwarden).
Secure first login: sign-ups disabled, random 24-character admin token stored only as an Argon2id hash, invite users from the admin panel (no SMTP needed), HTTPS through Apache and Let's Encrypt.

AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
If you are an AWS Free Tier customer with a free plan, you are eligible to subscribe to this offer. You can use free credits to cover the cost of eligible AWS infrastructure. See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.
You pay by the hour based on the EC2 instance type you run this managed password manager on. Pricing is usage-based, so you are billed only for the hours each instance runs. The dimensions map directly to AWS instance families — general purpose (m, t), compute (c), memory (r, x, z), storage (d, i), accelerated (g, p, inf, trn), and high-memory (u). Within each family, hourly rates scale with instance size, from small to the largest metal options. Choose an instance that fits your workload; larger sizes with more CPU and memory carry higher hourly rates.
Top-of-mind questions for buyers
Am I charged when the EC2 instance running the password manager is stopped or paused?
Software charges apply per hour the instance runs. A fully stopped instance does not accrue hourly software fees. Stopped instances may still incur underlying AWS storage charges for attached volumes, but the hourly rate in this listing meters running time only.
What does one hourly unit cover beyond the raw EC2 compute?
Each hour covers a dedicated, single-tenant instance of the managed password manager. The vendor handles provisioning, TLS certificates, daily backups with 30-day retention, managed version upgrades, and security patching. The software runs unmodified, and you can export your data at any time.
What drives my cost — the number of password manager users or the instance size?
Only the EC2 instance type and its running hours drive your cost. Billing does not change with user count, number of vaults, or usage volume. A heavily used instance costs the same hourly rate as a quiet one of the same size.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Initial release.
Application: Vaultwarden 1.37.5 (container image pinned, baked into the AMI).
Base: Ubuntu 24.04 LTS, fully patched at build time, built by an automated EC2 Image Builder pipeline.
TLS: Apache reverse proxy with a Let's Encrypt certificate requested by certbot at first login.
Credentials are generated on the instance at first login; none are present in the image.
Sign-ups are disabled; the admin panel is protected by a generated token (only its Argon2id hash is stored). Accounts are created by inviting an email address from the admin panel.
Additional details
Usage instructions
Launch an Instance
From AWS Marketplace, click Continue to Subscribe and then Continue to Configuration to launch the AMI.
Choose the Recommended Instance Type
Configure Security Group
Allow inbound traffic on the following ports:
22 (SSH) - terminal access for setup
80 (HTTP) - needed to validate your domain for the TLS certificate
443 (HTTPS) - access to Vaultwarden
Point a domain at the instance
Create a DNS A record (for example vault.example.com) pointing to the instance's public IP before you log in.
Connect to the Instance
ssh -i <your-key.pem> ubuntu@<public-ip>
First-Login Setup
The first SSH login runs a guided setup:
Prompts for your domain and admin email and checks the DNS A record
Generates a random 24-character admin token and stores only its Argon2id hash in the configuration
Starts Vaultwarden with sign-ups disabled and checks that the admin panel accepts the token
Configures Apache as an HTTPS reverse proxy and requests a Let's Encrypt certificate
Prints the URL and admin token and the steps to invite yourself and register; they are also stored in /opt/app/access.txt (root only)
If a step fails, fix the problem shown and log in again: the setup resumes where it stopped.
Access Vaultwarden
Sign-ups are disabled, so you create your own account by inviting yourself:
a. Open https://<your-domain>/admin and log in with the admin token printed at the end of setup
(view it again with: sudo cat /opt/app/access.txt).
b. Go to Users > Invite User and enter your own email address. No email server is needed.
c. Open https://<your-domain>, choose Create account, use that same email address and choose
your master password.
Invite any further users the same way. Anyone who has not been invited gets "Registration not allowed".
Credentials
Generated on your server, never shared between customers. View them again with:
sudo cat /opt/app/access.txt
Manage the Services
cd /opt/app
sudo docker compose ps
sudo docker compose restart
Create your account from the admin panel invitation as described above; further users are invited the same way. Your master password cannot be recovered. Data is kept in /opt/app/data; back it up regularly.
Thank you for subscribing.
