Using a password manager for SSH key storage

SSH keys authenticate developer and sysadmin access to servers, Git repositories, and infrastructure. They are credentials — often more powerful than passwords — and they carry the same credential management problem: multiple keys, no centralised storage, risk of loss, and no easy way to share controlled access with team members. Whether a password manager is the right storage solution for SSH keys depends on what you actually need to do with them.

Most password managers can store SSH private keys as secure notes or file attachments. Fewer integrate with the SSH agent to enable actual authentication workflows. The distinction matters: storing a key securely is different from using that key for SSH authentication without copying it to the filesystem.

Quick answer

You need SSH key storage with CI/CD integration

Keeper — Secrets Manager supports SSH key injection into automated pipelines

You want SSH key storage in an open-source vault

Bitwarden — keys stored as secure notes; no SSH agent integration, but auditable and self-hostable

When it matters

Secure backup — storing the private key in the vault provides an encrypted backup. If the key is lost from the local filesystem, you can retrieve it from the vault
Team sharing — sharing an SSH key with a team member through the vault is more controlled than email or Slack; access can be revoked when they leave
CI/CD injection — Keeper Secrets Manager can inject SSH keys into CI/CD pipeline environments at runtime, avoiding the need to store keys in environment variables or config files
No SSH agent integration in most managers — storing a key in Bitwarden means copying it to the filesystem before using it for SSH authentication; the vault is a storage layer, not an agent

When it fails

SSH agent workflows require copying keys to the filesystem — most managers don't integrate with ssh-agent. Retrieving the key from the vault for each use defeats the purpose of having an agent
Key rotation discipline — storing keys in a vault doesn't automate rotation. Old keys accumulate unless you have a rotation process
For production infrastructure access, consider dedicated PAM solutions — Vault, CyberArk, or BeyondTrust handle SSH key management at enterprise scale with features like session recording and just-in-time access that a password manager doesn't provide

How providers fit

Keeper provides the most complete SSH key management in this comparison. Keeper Secrets Manager supports programmatic SSH key access for CI/CD workflows. Keys can be stored, shared, and injected into pipelines without manual file handling.

Bitwarden provides secure SSH key storage as encrypted secure notes or file attachments. No SSH agent integration, but the open-source codebase is auditable, the CLI supports scripting, and self-hosting is available. Adequate for key backup and controlled sharing; insufficient for automated authentication workflows.

Bottom line

Keeper for production SSH key management with CI/CD integration. Bitwarden for SSH key backup and team sharing in smaller environments. For serious infrastructure secret management, evaluate whether Keeper Secrets Manager or a dedicated PAM tool is the right level — a standard password manager is a starting point, not a PAM replacement.
