Access all your passwords
with just a tap of fingerprint.
Engineered for people who demand absolute control over their digital lives — without sacrificing convenience.
Biometric Authentication
No one can clone it, steal it, or guess it — not even us. Your biometric data never leaves the device, so there's nothing to hack remotely.
Hardware-Level Security
Software can be hacked. ByteSeal adds a physical layer that malware, phishing, and remote attacks simply cannot reach.
Easily Portable
Same size as an ID card, same weight as a few coins. Carry military-grade security in your pocket — no bag, no bulk, no second thought.
AES-256 Encrypted Vault
Every password you store is encrypted with AES-256 — the same standard used by defence agencies and banks worldwide. Even if someone stole the data, it would be unreadable.
Offline biometrics
ByteSeal is never connected to the internet. Your biometric data is stored entirely on the device — invisible to hackers, immune to breaches, and impossible to intercept remotely.
Works on All Devices
Works seamlessly across Windows, macOS, iOS, and Android. Set it up once, and it just works — at your desk, on your phone, or on the move.

Frequently Asked Questions
Why should I trust Byteseal with my passwords?
Byteseal, unlike software only password managers, provides a hardware Biometric device as an additional security factor. This device is not connected to the internet in any way. Thus, all your Biometric data is stored in an offline secure environment.
Byteseal's system is engineered in a manner through which all the communications that happen between devices and Byteseal's systems are encrypted with military grade encryption. Thus, your passwords are never stored in the plaintext format anywhere in our systems. Only you, with your biometrics or through combination of OTP and PIN, can access your passwords.
What if my Byteseal Biometric ID is lost or stolen?
At Byteseal, we care about the integrity and confidentiality of the data of our customers more than anything else. In case the device is stolen or lost, then subject to prompt reporting by the customer, we will immediately disconnect your device from your profile so that nobody else can connect the device to your profile.
Also, all the biometric data which is stored in the device will still be secure and it will not be possible to reverse engineer it in any way.
How many fingerprints can be registered in the device
Users can register upto 5 fingerprints in the personal authentication device. We recommend registering fingerprints of both left and right hands.
What security measures are taken for protection of my data?
Byteseal works in a completely private network and all the communications that happens in this network are encrypted with world class military grade encryption algorithm (E.g. AES-256).
