After installing the Binance enterprise certificate version on an iPhone, opening it for the first time will prompt "Untrusted Enterprise Developer". This is a protection mechanism in iOS, requiring you to manually trust the issuer in the system settings before the APP can launch. This article provides the complete steps to get it done in 3 minutes. If you haven't obtained the latest installation package yet, you can first go to the Binance Official Website to download it, or get it through the iOS entry of the Binance Official App. For detailed pre-installation preparations, refer to the iOS Installation Tutorial.
Why Does iPhone Need to "Trust Certificate"?
iOS is very strict about APP installation sources. Apple only recognizes three legal sources:
- App Store (most common)
- TestFlight (Beta testing channel)
- Apple Developer Enterprise Program
The international iOS version of Binance is not listed on the App Store in many regions, so the 3rd method is commonly used—enterprise certificate signature distribution. For security reasons, Apple defaults to not allowing APPs signed with enterprise certificates to run. The user must proactively go into system settings and explicitly "trust" this certificate issuer for the APP to start.
This "trust" step is designed to prevent malicious enterprise certificate APPs from running without the user's confirmation.
Complete Steps to Trust the Certificate
Step 1: Confirm the APP is fully installed
First, long press the home screen to check if the Binance icon has appeared. If the icon hasn't appeared yet, it means the installation isn't complete, wait for the progress bar to finish before continuing.
Step 2: Tap the icon to attempt launching
Tap the Binance icon once on the home screen. At this point, iOS will pop up a warning:
"Untrusted Enterprise Developer" Your device management settings do not allow using apps from this developer...
Click "Cancel" to exit this warning.
Step 3: Open the "Settings" APP
Return to the home screen and open the system's Settings APP.
Step 4: Go to "VPN & Device Management"
Path on newer iOS (16/17/18): Settings → General → Scroll to bottom → VPN & Device Management
Path on older iOS (13/14/15): Settings → General → Profiles & Device Management
The names differ slightly, but the entry is always at the bottom of "General".
Step 5: Find the Enterprise App category
After entering "VPN & Device Management", you will see two sections:
- Configuration Profiles (VPN configs, MDM profiles, etc.)
- Enterprise App (The Binance certificate you just installed)
Tap the certificate issuer entry under "Enterprise App". This name might vary across different signature batches; it's usually an English string resembling a company name, like "Guangzhou XXX Technology".
Step 6: Tap "Trust"
After entering the certificate details page, there will be a blue button in the middle of the screen:
"Trust [Company Name]"
Tap this button. The system will pop up a secondary confirmation box:
"Trust apps from '[Company Name]' on this iPhone" Trusting will allow any app from this enterprise developer to be used on your iPhone and may allow access to your data.
Tap "Trust" to confirm.
Step 7: Check verification
After successfully trusting, a green "Verified" indicator will appear on the certificate details page. This means iOS has confirmed the validity of this certificate.
Step 8: Return to home screen to open Binance
Exit the Settings APP, and tap the Binance icon on the home screen. This time there will be no warning, the APP will launch normally and enter the login/registration page.
Troubleshooting Common Blockers
Blocker 1: Cannot find the "Enterprise App" category
If there is no "Enterprise App" item in VPN & Device Management, it means:
- The APP hasn't finished installing; wait for it to finish.
- The APP didn't install at all; go back and check the download and installation process.
- You installed the App Store version or TestFlight version, which do not require trusting a certificate.
Blocker 2: The "Trust" button is grayed out and cannot be tapped
iOS requires the device to be connected to the internet when trusting, because Apple verifies the certificate status online.
- Turn on Wi-Fi or cellular data.
- If in "Airplane Mode", turn it off.
- The system time must be correct; an incorrect time will cause certificate verification to fail.
Blocker 3: Tapped trust but still cannot open the APP
Possible situations:
- The certificate was just revoked by Apple at that moment (bad luck)—you need to download a newly signed version.
- iOS cache hasn't refreshed—restart your iPhone and try again.
- Conflict between multiple APPs with the same signature—uninstall other APPs sharing the same certificate.
Blocker 4: Tapping the certificate shows "Verification Required"
In rare cases, the system prompts:
This app cannot be used unless it is verified. To allow this app to be used on this iPhone, tap "Verify App".
Tap "Verify App", wait a few seconds, and it will enter the trust interface. This step also requires an internet connection.
How Long Until the Trust Expires?
Enterprise certificates have a validity period:
- Apple enterprise developer certificates last up to 1 year.
- Apple may actively revoke non-compliant certificates at any time.
- Once a certificate is invalidated, all APPs signed with it simultaneously fail to open.
If one day you open Binance and it prompts "App needs to be updated" or simply crashes, it's highly likely that the certificate has expired or been revoked. When this happens, you need to download a newly signed version and go through the trust process again.
Security Precautions for Trusting Certificates
1. Only trust signatures from official Binance
Do not trust Binance certificates from unknown sources. Some "internal versions" or "cracked versions" floating online might be maliciously signed. After trusting, enterprise certificates have very high permissions, equivalent to you authorizing this developer to run any code on your phone.
2. Periodically check trusted certificates
Go to Settings → General → VPN & Device Management → Enterprise App, and periodically check if there are any certificates you don't recognize. If there are, you might have accidentally installed APPs from unknown sources.
3. Promptly delete unused certificates
After uninstalling an APP, its profile is not automatically deleted. When no longer needed, enter the certificate details page and tap "Delete App" to thoroughly clean it up.
4. Do not share profiles with strangers
Profiles contain signature information. If others obtain it, they can use it to sign any APP and pretend to be Binance, posing a phishing risk.
Enterprise Certificate vs. TestFlight vs. App Store
| Dimension | Enterprise Certificate | TestFlight | App Store |
|---|---|---|---|
| Needs Trusting? | Yes | No | No |
| Expiry Risk | High | None | None |
| Auto Update | Manual | Auto | Auto |
| Ease of Install | Fair | Good | Best |
| Region Limits | Fewer | Slot Limit | Based on Store |
For most users in overseas regions, direct installation from the App Store is the top choice. If there is truly no App Store channel available, then consider TestFlight, and only as a last resort use the enterprise certificate.
Frequently Asked Questions
Q: Will trusting the certificate leak my iPhone data?
A: Trusting an enterprise certificate means authorizing the developer's APP to run like a normal APP, not giving the developer access to your entire disk data. As long as the APP itself is genuine Binance, it is safe. The key is not to trust certificates from unknown sources.
Q: Why does the APP still crash after I trusted it?
A: It might be because the certificate has been revoked by Apple but your local device hasn't synced yet. Open Safari and visit any website to trigger a network connection, then reopen the APP; if that doesn't work, restart the iPhone.
Q: Do I need to trust it again every time I open it?
A: No. Trusting is a one-time action. Opening the APP afterwards will not prompt you again until the certificate expires or you actively delete it.
Q: Can I bypass the trust step and launch the APP directly?
A: No. This is a mandatory iOS system mechanism with no legal way to "bypass". Jailbreaking can bypass it but brings severe security risks.
Q: Will trusting a certificate affect my Apple ID?
A: Not at all. Trusting an enterprise certificate is a device-level operation, unrelated to the Apple ID account, and will not be recorded to iCloud.
