UnveilPass vs Sticky Password: A Feature-by-Feature Comparison

Sticky Password has been around since 2001, making it one of the longest-running password managers on the market. It earned a loyal following thanks to a feature that remains rare today: the ability to sync your vault exclusively over your local WiFi network without ever touching a cloud server. For privacy-conscious users, that has always been a compelling proposition.

UnveilPass takes a different approach. It is a cloud-based password manager built from the ground up on zero-knowledge architecture. The server stores only ciphertext and can never see your passwords, notes or personal data. Both tools solve the same fundamental problem but make very different trade-offs to get there.

This article compares the two side by side so you can decide which one fits your workflow and threat model.

Architecture: Cloud Zero-Knowledge vs WiFi-Only Sync

The biggest architectural difference between these two managers is how they handle synchronization across devices.

Sticky Password gives you a choice. You can sync your vault through their cloud servers or you can restrict sync to your local WiFi network only. The WiFi-only mode means your encrypted vault never leaves your home or office network. There is no web vault, no remote access and no data on third-party servers. For users who fundamentally distrust cloud storage, this is the gold standard.

UnveilPass is cloud-only but compensates with a strict zero-knowledge design. Your master password never leaves your device. The server receives only a derived authentication key (not your password) and stores your vault as AES-256-GCM ciphertext that it cannot decrypt. All encryption and decryption happens in your browser or extension using Web Crypto API and Argon2id WASM. Even your email address is encrypted at rest on the server.

Sticky Password uses AES-256 encryption, which is industry standard. However, its key derivation process is less publicly documented compared to UnveilPass, which uses Argon2id — the winner of the Password Hashing Competition and the current best practice for deriving encryption keys from passwords. Argon2id is specifically designed to resist GPU and ASIC brute-force attacks by requiring large amounts of memory.

The Sticky Password Advantage: WiFi Sync and Lifetime License

Credit where it is due — Sticky Password has two features that are genuinely unique in the password manager market.

WiFi-only synchronization is the headline feature. If you have a desktop computer and a laptop on the same network, Sticky Password can sync your vault between them over your local WiFi without any data passing through the internet. This is not just a marketing claim — it is a fundamentally different sync model. Your vault data stays within the physical boundaries of your network.

The trade-off is significant. You cannot access your passwords from a hotel, a coworking space or your phone on cellular data unless your devices have recently synced at home. There is no web vault to fall back on. If your laptop dies, recovery depends on having another synced device on the same network.

The lifetime license is another standout. For $99.99 (one-time payment), you get Sticky Password Premium forever with no recurring charges. In a market dominated by annual subscriptions, this appeals to users who prefer to pay once and forget about renewals. At $39.99 per year for the annual plan, the lifetime license pays for itself in under three years.

Sticky Password also supports Safari as a browser extension — something UnveilPass does not currently offer. For Mac users who rely on Safari as their primary browser, this matters.

Finally, Sticky Password donates a portion of every license sale to manatee conservation through the Save the Manatee Club. It is a small detail but a charming one that reflects the company's long history and personality.

Feature-by-Feature Comparison

Where Sticky Password Wins

Sticky Password holds clear advantages in several areas:

• WiFi-only sync — No other mainstream password manager offers true local-network-only synchronization. If your threat model requires zero cloud involvement, Sticky Password is one of your only options.
• Lifetime license — A one-time purchase of $99.99 eliminates subscription fatigue. For individual users who plan to stick with one tool for years, this is exceptional value.
• Safari extension — Mac users who prefer Safari get native extension support. UnveilPass currently supports Chrome, Edge and Firefox only.
• Opera extension — Sticky Password covers an additional browser that UnveilPass does not.
• Track record — Twenty-five years in the market (since 2001) provides a level of proven stability that newer tools cannot claim.
• Manatee conservation — A portion of every purchase goes to the Save the Manatee Club, which is a genuinely endearing initiative.

Where UnveilPass Wins

UnveilPass has the edge in security depth and feature breadth:

• Argon2id key derivation — The gold standard for password hashing, purpose-built to resist GPU and ASIC attacks. PBKDF2 (used by Sticky Password) is older and less resistant to modern hardware.
• Email encryption at rest — Your email address is encrypted on the server using AES-256-GCM with a SHA-256 hash for lookups. Sticky Password stores emails in plaintext.
• Built-in TOTP authenticator — Store and generate two-factor authentication codes directly in your vault entries. No need for a separate authenticator app.
• Phishing and malware protection — The browser extension actively blocks known phishing and malware domains. Sticky Password does not offer this.
• Emergency Access — Designate trusted contacts who can request access to your vault if you become incapacitated. Sticky Password has no equivalent feature.
• Recovery QR Code — A PIN-encrypted QR code that lets you recover your master password without the server ever knowing it. No similar mechanism exists in Sticky Password.
• Device Trust — New devices must be verified with an email code before they can access your vault, adding a layer of protection against stolen credentials.
• Real free plan — UnveilPass Free gives you 10 vault entries with no expiration date. Sticky Password only offers a 30-day trial before requiring payment.
• Richer identity types — Six specialized identity types (address, bank account, credit card, document, insurance, medical) versus Sticky Password's two basic types.
• Team encryption — Team keys are encrypted via X25519 ECDH per member, maintaining zero-knowledge even in team scenarios.
• Lower annual price — At $19.95 per year, UnveilPass Pro costs half of Sticky Password's $39.99 annual plan.

Security Architecture Compared

Both tools encrypt your vault with AES-256 and both ensure your master password is never transmitted to their servers. The differences are in the details.

UnveilPass derives your encryption key using Argon2id with 64 MB of memory, 3 iterations and 4 parallel lanes. This produces a 64-byte hash: the first 32 bytes become your authentication key (re-hashed server-side) and the remainder is fed through HKDF-SHA256 to produce your Key Encryption Key (KEK). Your actual vault key is a random AES-256 key wrapped with the KEK. This layered approach means changing your master password only requires re-wrapping the vault key — not re-encrypting every entry.

Sticky Password uses PBKDF2 for key derivation. While PBKDF2 is widely used and approved by NIST, it does not have the memory-hard properties of Argon2id. This makes it theoretically more vulnerable to attacks using specialized hardware such as GPUs or ASICs that can run millions of PBKDF2 iterations in parallel.

On the sharing front, UnveilPass uses X25519 ECDH to derive a shared key between sender and recipient. This means even shared entries remain end-to-end encrypted — the server never holds a key that could decrypt shared data. Sticky Password's sharing is more straightforward but less cryptographically documented.

The WiFi Sync Trade-Off

Sticky Password's WiFi-only mode deserves a deeper look because it represents a genuine philosophical choice about security.

When you choose WiFi-only sync, your vault data never touches a server you do not control. This eliminates an entire category of risk: server breaches, cloud provider compromises and government data requests to the password manager company. Your data lives on your devices and moves between them only on your local network.

The costs are real though:

• No remote access — You cannot look up a password from a hotel or airport unless your device was recently synced at home.
• No web vault — There is no browser-based interface to fall back on if you do not have the app installed.
• Manual sync discipline — You need to remember to sync devices regularly while they are on the same network.
• Recovery risk — If all your synced devices are lost or destroyed, your vault is gone. There is no server-side backup to restore from.

UnveilPass addresses these concerns differently. Your vault is always available from any device with a browser because it syncs through the cloud. But the zero-knowledge design means the cloud server is cryptographically unable to read your data. You get the convenience of cloud sync with a mathematical guarantee that the server operator cannot access your vault — even under legal compulsion.

Pricing and Plans

Sticky Password offers three options: a 30-day free trial, an annual plan at $39.99 per year and a lifetime license at $99.99 (one-time payment). There is no permanent free tier. After the trial, you must pay to continue using the product.

UnveilPass has a genuine free plan with 10 vault entries and 10 secure notes — no time limit. The Pro plan costs $19.95 per year and unlocks unlimited entries, teams, breach scanning, attachments and custom fields. There is no lifetime license option.

For users who commit to the long term, Sticky Password's lifetime license becomes cheaper than UnveilPass after year five ($99.99 vs $99.75 cumulative). For shorter time horizons, UnveilPass is more affordable. And for users who just need a few passwords managed securely, UnveilPass Free costs nothing at all.
