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. 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.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 āCobo Portal Mobile / Portal Mobileā to distinguish it from Cobo Portal (web).
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.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 deviceās security mechanisms.
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.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 Mobileās Approvals tab. The following table lists operations that require other membersā approval through Portal Mobile:| Module | Operation |

- 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.
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.Currently, Cobo Portal Mobile is primarily intended for newly registered users. Accounts that have already been bound to Cobo Guard cannot yet complete device binding in Portal Mobile, and will see a corresponding message after logging in. For details, see Migrate from Cobo Guard.
Recommendations during the coexistence period
- If you are currently using Cobo Guard, continue using Cobo Guard ā there is no need to switch immediately. Migrate once the official migration path is available.
- If you are a new user or a new organization, we recommend using Cobo Portal Mobile directly.
- Watch for migration announcements from Cobo, and proceed once the migration path is available.
