## What is Cobo Portal Mobile

Cobo Portal Mobile (hereinafter referred to as **Portal Mobile**) is a next-generation mobile solution developed by Cobo for institutional users of [Cobo Portal](/en/portal/introduction). It brings identity authentication, operation approval, MPC key share management, and day-to-day asset management together in one place, and supports both **iOS and Android** devices.

Free for all Cobo Portal users, Portal Mobile is both the security hub of your account and your mobile entry point for viewing assets, initiating transactions, and approving operations anytime, anywhere.

<Note>Cobo Portal Mobile is published in the App Store and Google Play under the name **Cobo Portal**. This documentation consistently refers to Portal Mobile as "Cobo Portal Mobile / Portal Mobile" to distinguish it from **Cobo Portal (web)**.</Note>

## Why we designed Cobo Portal Mobile

### Asymmetric encryption for identity and approval

When you bind a device, Portal Mobile generates an identity key pair on that device. The public key is shared with Cobo to verify your identity, while the private key is stored in a secure storage area on the device and never leaves it. All identity authentication (MFA) and operation approvals are signed by this private key and verified through the public key you share with Cobo.

### MPC key share mechanism for asset security

For MPC Wallets, Portal Mobile uses multi-party computation (MPC / TSS) technology. A complete private key is split into multiple **key shares** distributed across different parties or devices. No single entity can independently hold the complete private key, eliminating single points of failure. Your key shares are generated, backed up, and restored on your device, and the shares themselves never leave the device in plaintext.

### Device-level security

To use Portal Mobile, your device must have a screen lock enabled, and we recommend enabling biometrics (Face ID / fingerprint). Portal Mobile automatically locks after being in the background for a period of time, and requires biometric authentication to re-enter, adding another layer of protection for your account and assets.

<Note>We take security very seriously. Unlike Cobo Guard, which supports iOS only, Portal Mobile supports both iOS and Android. Regardless of the platform, key shares always remain on the device and are protected by the device's security mechanisms.</Note>

## Key features

### Multi-factor authentication (MFA) method

Multi-factor authentication (MFA) adds an extra layer of security to Cobo Portal by requiring a second verification step beyond your password. This helps prevent unauthorized access, even if your password is compromised.

Portal Mobile acts as an MFA option, allowing you to quickly verify logins and sensitive operations, such as inviting new users or modifying risk controls. With a simple confirmation in Portal Mobile, you can verify your identity and keep your account protected.

### MPC key share manager

Securely generate, back up, and manage MPC key shares to strengthen asset protection and minimize the risk of single points of failure. By distributing key shares across multiple parties or devices, Portal Mobile ensures that no single entity has full control over private keys, enhancing overall security.

Key shares can be backed up to **iCloud**, **Google Drive**, or exported as a **local file**, and are encrypted during backup with a recovery passphrase that you set.

For details on generating and backing up key shares, refer to [Generate and back up your key shares](/en/portal-mobile/generate-and-back-up-key-shares).

### Operation approval

Portal Mobile allows you to approve operations initiated by other users within the organization, such as transactions, organization management, and risk control changes. This ensures that sensitive actions undergo proper oversight before being executed.

Certain operations, based on risk control settings, require approval from designated members. Portal Mobile notifies approvers via push notifications, enabling them to review and authorize requests directly in Portal Mobile's **Approvals** tab.

The following table lists operations that require other members' approval through Portal Mobile:

### Asset and transaction management

Beyond security features, Portal Mobile also provides full mobile asset management capabilities:

* **View wallets and balances**: Browse the wallet list, token holdings, and balances in your organization.
* **Receive**: Display wallet addresses and receiving QR codes.
* **Transfer and withdraw**: Initiate transfers on mobile, review transaction details, and sign with biometrics.
* **Transaction history**: View transaction history and the details of individual transactions.

## Relationship with Cobo Guard

Cobo Portal Mobile is the **next-generation replacement** for Cobo Guard. Portal Mobile covers all of Cobo Guard's security capabilities (MFA, MPC key share management, operation approval), and additionally extends cross-platform support, asset and transaction management, and multi-cloud backup.

### Old and new relationship

* **Cobo Guard (old)**: The existing product, available for iOS only, a security companion product for Cobo Portal.
* **Cobo Portal Mobile (new)**: The next-generation product, available for iOS and Android, which can fully replace Cobo Guard and further extends its capabilities.

The two are **two separate products**, not different versions of the same product.

### Migration direction

In the future, Cobo Guard users will gradually migrate to Cobo Portal Mobile. Before the migration path is officially available, the two products will coexist in parallel for a period of time.

<Warning>**Current limitation — new users only, no migration from Cobo Guard yet.** Cobo Portal Mobile is currently **only available to newly registered users / new organizations**. Accounts that have **already been bound to Cobo Guard cannot complete device binding in Portal Mobile**, cannot generate key shares in Portal Mobile, and cannot migrate from Cobo Guard to Portal Mobile at this time. After logging in, they will see a message such as "Cobo Portal is currently limited to newly registered users". For details, see [Migrate from Cobo Guard](/en/portal-mobile/migrate-from-guard).</Warning>

### Recommendations during the coexistence period

* If you are currently using **Cobo Guard** (existing user / existing organization already bound to Cobo Guard), **you must continue using Cobo Guard** — Portal Mobile **does not yet support you**. Do **not** try to log in to Portal Mobile to "switch" or "migrate"; it will not let you bind your device. Wait for the official migration path to be released.
* If you are a **new user or a new organization** that has never been bound to Cobo Guard, we recommend using Cobo Portal Mobile directly.
* Watch for migration announcements from Cobo, and proceed once the migration path is available.
