How to Manage Trusted Devices in the Binance APP

Trusted Devices: The Balance Between Security and Convenience

Every time you log into the Binance APP on a new device, you must go through a series of security verifications: entering your password, email verification code, SMS code, Google Authenticator code... the whole process takes at least two minutes. For devices you use occasionally, this strict verification is necessary. But what about the phone you use every single day?

That is what the "Trusted Device" feature is designed for. Once you mark your regular device as "trusted," subsequent logins can skip some of the verification steps, dramatically improving usability without reducing overall security.

Trusted Device vs. Standard Device

Standard Device (Not Trusted)

Login process:

1. Enter account credentials and password
2. New device detected — verification email/SMS sent
3. Enter email verification code
4. Enter SMS verification code
5. Enter Google Authenticator code
6. Login successful

Trusted Device

Login process:

1. Enter account credentials and password
2. Enter Google Authenticator code (or use biometric authentication)
3. Login successful

As you can see, a trusted device skips the new-device detection and email/SMS confirmation steps, but still requires a password and two-factor authentication. This is a carefully considered security design — even when a device is trusted, core verification is never bypassed.

How to Set a Device as Trusted

Method 1: Choose to Trust During Login

1. Complete the full login process on a new device
2. After successfully logging in, the system may display a prompt: "Would you like to set this device as a trusted device?"
3. Tap "Trust This Device"
4. The device is added to the trusted list

Method 2: Add via Security Settings

1. Open the Binance APP → Profile avatar → "Security"
2. Find "Device Management" or "Trusted Devices"
3. In the list of logged-in devices, find the device you want to trust
4. Tap to set it as a trusted device
5. Complete security verification

Managing the Trusted Device List

Viewing Trusted Devices

1. Go to "Security" → "Device Management"
2. The device list will indicate which devices have "Trusted" status
3. These are usually identified by a special icon or label

Removing Device Trust

When you no longer use a particular device:

1. Find that device in the device management list
2. Tap "Untrust" or "Remove"
3. Complete security verification
4. The next login from that device will require the full verification process

Recommended Management Principles

1. Only trust personal devices you use long-term (typically 1–2 devices)
2. Do not trust public devices (internet cafe computers, hotel iPads, etc.)
3. Do not trust borrowed devices
4. Remove trust before selling or giving away a device
5. Review the trusted device list regularly (once a month)

Security Mechanisms Behind Trusted Devices

Device Fingerprint Binding

Trusted devices are recognized based on a device fingerprint, which includes:

• Hardware identifiers (device ID)
• Operating system information
• App installation identifier
• Encrypted token (stored in the device's secure enclave)

This means:

• After a factory reset, the device fingerprint changes and re-trusting is required
• Reinstalling the Binance APP may require re-trusting
• Flashing a new ROM on the same phone also requires re-trusting

Trust Validity Period

The trusted status of a device typically has a validity period:

• In most cases, if you have not logged in on that device for 30 days, the trusted status may expire automatically
• Certain security policy changes (such as modifying your password) will reset the trusted status of all devices
• Security policy updates on Binance's servers may also affect trusted status

Anomaly Detection Override

Even if a device is marked as trusted, additional verification will still be triggered if the system detects unusual activity:

• Login IP significantly different from previous logins
• Abnormal login time patterns
• Changes in the device environment (such as jailbreak/root detection)
• Other security risks associated with the account

Trust Strategies for Different Scenarios

Scenario 1: Only One Phone

Simply set that phone as a trusted device. This is the simplest and safest scenario.

Scenario 2: Phone + Tablet

Set both devices as trusted. Keep in mind:

• If the tablet is rarely used, there is no need to trust it
• A tablet shared by family members should not be set as trusted

Scenario 3: Phone + Browser (Web Version)

Set the phone as a trusted device. For the desktop browser, it is generally recommended not to set it as trusted (unless it is your personal computer with comprehensive security protection), since computers are more susceptible to malware.

Scenario 4: Frequently Changing Phones

If you change phones often, the recommended approach is:

1. Set the new phone as trusted immediately after logging in
2. Remove the old phone from the trusted list immediately
3. Review the trusted device list after every phone change

What to Do If Your Trusted Device Is Lost

If the phone you set as trusted is lost or stolen:

Step 1: Remotely Lock the Phone

• iOS: Remotely lock via "Find My iPhone"
• Android: Remotely lock via "Find My Device"
• If possible, remotely erase the phone's data

Step 2: Log Into Binance from Another Device

1. Log in using another device (full verification required)
2. Go to Device Management
3. Remove the lost trusted device
4. You can also choose "Log Out of All Devices"

Step 3: Security Review

1. Change your password
2. Check for any suspicious activity
3. Confirm all security settings are intact

Step 4: Follow-Up Actions

1. If the phone is recovered, re-add it as a trusted device
2. If the phone cannot be recovered, ensure all the above security steps are completed
3. Once your new phone is set up, add it as a new trusted device

Frequently Asked Questions

Is Google Authenticator still required after setting a device as trusted?

Yes. The trusted device feature only skips the new-device detection and some email/SMS verification steps. Google Authenticator, as a core security layer, is still required.

Can trusted status be revoked automatically?

It may be revoked automatically under the following circumstances:

• No login on that device for an extended period
• Account password was changed
• System security policy update
• The app was uninstalled and reinstalled

Is there a limit on the number of trusted devices?

Binance has not publicly stated a specific limit, but it is advisable to keep it to no more than 3. Having too many trusted devices increases the attack surface.

Can a jailbroken/rooted phone be set as a trusted device?

Technically it may be possible, but it is strongly discouraged. The security of a jailbroken/rooted device is significantly compromised, making it easier for malware to access sensitive data. The Binance APP may also detect the jailbreak/root status and restrict certain features.

Trusted Devices and Their Relationship to Other Security Features

Summary

The trusted device feature is a clever security design: it acknowledges your regular devices and streamlines the login process without compromising core security verification. The key lies in thoughtful management — only trust devices under your own control, review the trusted list regularly, and remove devices promptly if they are lost. Using this feature correctly lets you enjoy both security and convenience at the same time.
