A Modern Bitwarden Alternative for Developers

Bitwarden built the open-source standard. PassCryp picks up where it left off: modern AES-256-GCM + Argon2id (Bitwarden defaults to PBKDF2), first-class API key storage, and a UX rebuilt for developer workflows.

Start your free vault Security model

AES-256-GCM, not CBC

Authenticated encryption that detects tampering. Bitwarden uses AES-256-CBC + HMAC; PassCryp uses GCM natively.

Argon2id by default

Bitwarden defaults to PBKDF2 (Argon2 is opt-in). PassCryp uses Argon2id at OWASP-recommended parameters by default.

First-class API key vault

Provider-aware AWS, Stripe, OpenAI, GitHub storage with expiry alerts. Beyond Bitwarden's generic secure notes.

Direct Bitwarden import

Bitwarden JSON export imports with folder structure and items intact.

Open-source browser extension

Audit every line that touches your master password. Same transparency story as Bitwarden.

Free tier with unlimited devices

Same generous free tier as Bitwarden — without the dated UI.

Where Bitwarden and PassCryp diverge

Bitwarden is the open-source bedrock — one of the best free password managers available. PassCryp's pitch isn't "better than Bitwarden everywhere"; it's "more modern crypto stack, developer-first feature set, snappier UX."

On crypto: Bitwarden defaults to AES-256-CBC + HMAC + PBKDF2. PassCryp uses AES-256-GCM (authenticated, hardware-accelerated) + Argon2id (memory-hard) by default. Bitwarden has Argon2 as opt-in; PassCryp ships it as the only option.

On features: PassCryp's API Key Vault is purpose-built for developer secrets in a way Bitwarden's secure notes aren't. The CLI (beta) integrates directly into shell workflows. The UX is faster and feels current.

Self-hosting

If self-hosting is a hard requirement, stay on Bitwarden — Vaultwarden is excellent. PassCryp is hosted-only today. A self-host build is on the roadmap; the browser extension is already open source.

If you don't actually need self-hosting (most teams don't) and you'd rather have a modern crypto stack and developer features, PassCryp is the answer.

Migrating from Bitwarden

Export Bitwarden as JSON (preferred over CSV — preserves folder structure and item types). Tools > Export Vault > File Format JSON.

In PassCryp: sign up, set a master password, download recovery kit. Open Import, pick Bitwarden JSON, upload. Folders, logins, secure notes, identities, and cards map cleanly.

Verify, then delete the JSON export (overwrite, don't trash) and disable the Bitwarden account.

Frequently asked questions

Is PassCryp open source like Bitwarden?

The browser extension is open source. The core vault uses a documented zero-knowledge architecture in our security whitepaper. A self-host build is on the roadmap.

Why pick PassCryp over Bitwarden?

Modern AES-256-GCM + Argon2id by default, first-class API key vault, snappier UX, and a CLI built for developers.

Is GCM safer than CBC?

GCM is authenticated — tampering with ciphertext is detected. CBC alone is not, which is why Bitwarden pairs it with HMAC. Both are secure in practice; GCM is the modern best-practice.

Can I self-host PassCryp?

Not yet. If self-hosting is required today, Vaultwarden is a great option. PassCryp's hosted product uses managed infrastructure with per-row encryption.

Does PassCryp support CLI like Bitwarden?

A CLI is in private beta. The extension already supports headless workflows for scripted use.

Is PassCryp also free?

Yes — free tier covers 100 items with unlimited devices, the browser extension, generator, TOTP, and breach checks.
