PassCryp vs Keeper

PassCryp encrypts every vault item on your device with AES-256-GCM — an authenticated encryption mode that detects tampering. Your master password is never transmitted; it derives a vault key locally using Argon2id, a memory-hard KDF designed to defeat modern GPU and ASIC brute-force attacks.

Sync is built on encrypted ciphertext only. Even a full database compromise would expose no plaintext, because the keys live in your head — not on our servers. Per-row Row-Level Security in the database adds a second layer: a misconfigured query physically cannot return another user's ciphertext.

The browser extension is open source so you can audit the code that touches your master password. The core vault architecture is documented in a public security whitepaper, and every dependency that touches cryptography is pinned and reviewed.

PassCryp Free covers 100 vault items, unlimited devices, the browser extension, the password generator, and TOTP — at $0 forever. Premium is $2.99/month for 200 items, API key storage with expiry alerts, the credit card vault, and priority support.

Keeper starts at $2.92/month for Personal. The gap widens once you add teams, families, or premium-only features like dark-web monitoring. PassCryp ships breach-checking on every plan via the HIBP k-anonymity API — only the first 5 characters of a password hash ever leave your device.

There are no per-seat enterprise tiers, no sales-only quotes, and no dark-pattern downgrades. Cancel any time from your account page; your encrypted vault stays accessible on the free plan.

Sign up for a free PassCryp account in under 60 seconds — no credit card, no trial timer. Set a strong master password (we recommend 4+ random words) and download your one-time recovery kit.

Export your existing Keeper vault to CSV or JSON from its desktop or web app. The export contains your items in plaintext, so do it on a trusted machine and delete the file after import.

Open PassCryp's Import wizard from the vault menu, choose the Keeper preset, and upload the export. Field mapping is automatic: titles, usernames, passwords, URLs, notes, and TOTP seeds all carry over. Review the diff, click Import, and your vault is live across every device.
