Your Identity. Your Authority. Your Control.
Authenticate without passwords, control credentials, review delegated authority, approve sensitive actions, and manage supported payments from a trusted device.
Authentication & Approval
Prove who you are and approve what matters — no passwords required.
The PTERI App was designed for security workflows, not trading. It provides what other apps do not:
It is not just a wallet
it is your personal authorization device for the digital world.
Biometric Approval
Approve sensitive actions using Face ID, Touch ID, Android biometrics, and secure enclave hardware.
Your device becomes your approval mechanism.
Passwordless Authentication
PTERI App doubles as your authentication device to approve logins and sign authorization challenges.
Your device becomes your passwordless credential.
Passwordless Authentication Device
PTERI uses your device as your cryptographic credential — no passwords needed.
Customer-Controlled Credentials
Your keys and credentials stay on your device. We never have access.
Customer-Controlled Keys
Private keys never leave the device. We cannot access your wallet.
Your keys stay in your hands.
Encrypted Key Storage
AES-256 encryption and on-device key storage keep your Litecoin payment credentials private.
Security by design.
Encrypted Backups
Optional end-to-end encrypted backups controlled by the user, protected with AES-256.
Backups only you can decrypt.
Manage On-Device Identity
Your device holds your identity. No centralized username or password required.
Why Users Trust PTERI App
- No tracking
- No ads
- No analytics
- No data collection
- No shared secrets
Customer-controlled credentials and cryptographically verifiable authorization.
Sensitive-Action Workflow
Every high-risk action follows the same trusted approval path.
Request received
A login, payment, or delegated agent action arrives that requires your authorization.
Review and approval
Review who is asking, what they want to do, and the scope of access — then approve, or trigger step-up verification for higher-risk actions.
Evidence created
A cryptographically signed record of your approval is created as auditable evidence, without ever exposing your keys.
Approve Sensitive Actions
Step-up approval for high-risk operations and delegated authority.
