# Authentication & Security

{% hint style="info" %}
Operator and jurisdiction: BASIS is operated by BASIS DIGITAL INFRASTRUCTURE LTD, a Seychelles IBC (LEI: [254900IX2F2KCWNSSS64](https://lei.bloomberg.com/leis/view/254900IX2F2KCWNSSS64)).
{% endhint %}

BASIS uses passwordless login and enforces strict session controls. Every account follows the policies on this page. These controls operate within an institutional-grade security and service management framework maintained by an internationally certified operator.

***

## 1. Passwordless Login

BASIS does not use usernames and passwords.

Login uses email-based one-time verification codes (OTP):

{% stepper %}
{% step %}
Enter your email address on the login screen.
{% endstep %}

{% step %}
BASIS sends a 6-digit verification code to your email.
{% endstep %}

{% step %}
Enter the code to access your account.
{% endstep %}
{% endstepper %}

This reduces common password-related attack vectors such as credential stuffing, password reuse, and brute-force attempts.

{% hint style="warning" %}
BASIS will never ask for your password, seed phrase, or private key.
{% endhint %}

***

## 2. Verification Code Validity

| Property        | Value                                                      |
| --------------- | ---------------------------------------------------------- |
| Code length     | 6 digits                                                   |
| Validity period | 10 minutes from issuance                                   |
| Reusable        | No, single use only                                        |
| Scope           | Valid only for the login session in which it was requested |

After the validity window closes, the code no longer works. A new login request generates a new code.

{% hint style="info" %}
If you receive a verification code email that you did not request, you can ignore it. No account access occurs unless the code is entered successfully.
{% endhint %}

***

## 3. Single Active Session Policy

BASIS enforces a Single Active Session Policy:

* When the same account logs in from another device or browser, BASIS terminates the existing session.
* Only the most recent session remains active.
* If your session is terminated, log in again to continue.

This control limits concurrent account access and reduces session-sharing risk.

***

## 4. Login Notifications

BASIS sends a one-time verification code to your email for each login. There is no separate login notification email. If you did not request a login code, do not enter it and contact <support@basis.pro> immediately.

***

## 5. Your Security Responsibilities

You remain responsible for the security of your login environment.

* Protect your email account. OTP delivery depends on inbox security. Enable 2FA with your email provider.
* Do not share verification codes. BASIS support will never ask for your OTP.
* Log out on shared or public devices after each session.
* Report suspicious activity immediately to <support@basis.pro>.

{% hint style="success" %}
Your email account is the primary access control layer for BASIS. If your email is compromised, your account may be at risk.
{% endhint %}

## 6. Platform Security Principles

BASIS applies the following controls through an institutional-grade operating model supported by BASIS DIGITAL INFRASTRUCTURE LTD's active ISO/IEC 27001:2022 and ISO/IEC 20000-1:2018 management system certifications.

| Principle                       | Implementation                                                                                                                                 |
| ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| OTP-based authentication        | No stored passwords. Each login requires a fresh code                                                                                          |
| Single active session           | Concurrent sessions are not permitted                                                                                                          |
| Login environment alerts        | Email notifications for login events                                                                                                           |
| Anomaly detection               | Automated systems monitor unusual access patterns                                                                                              |
| Deterministic infrastructure    | State-machine risk controls, math-constrained execution paths, and deterministic session handling                                              |
| Institutional-grade systems     | N+1 bare-metal failover and BHLE infrastructure                                                                                                |
| Information security governance | Security processes operated within the ISO/IEC 27001:2022 certified Information Security Management System of BASIS DIGITAL INFRASTRUCTURE LTD |
| IT service management           | Service operations managed within the ISO/IEC 20000-1:2018 certified IT Service Management System of BASIS DIGITAL INFRASTRUCTURE LTD          |

## 7. BHLE Cryptographic Asset Enclave

BHLE is BASIS’s proprietary routing and execution infrastructure, designed for deterministic execution, structural alpha capture, and controlled system isolation.

Core properties include:

* Sub-50μs latency
* 100K+ OPS throughput capacity
* Proprietary routing infrastructure
* State-machine risk controls
* Math-constrained execution paths

The Cryptographic Asset Enclave is designed so that:

* User assets reside in a mathematically isolated environment.
* Asset control remains logically separated from the execution layer.
* BHLE generates execution instructions without direct signing authority.
* Sensitive authorization boundaries are isolated from central platform orchestration.

This design helps ensure that execution infrastructure and asset authorization remain separated by system constraints rather than operator discretion alone.

{% hint style="info" %}
BASIS security architecture is informed by research collaboration with Base58 Labs and emphasizes deterministic execution, bounded system behavior, and infrastructure-level fault isolation. These principles operate within BASIS DIGITAL INFRASTRUCTURE LTD's active ISO/IEC 27001:2022 certified Information Security Management System and ISO/IEC 20000-1:2018 certified IT Service Management System, with public verification available through IAF CertSearch.
