Why Two-Factor Authentication Matters
Your api228 account contains sensitive information: your verified identity documents, linked payment methods, transaction history, and account balance. A strong password alone is insufficient to protect this data. Attackers can acquire passwords through phishing emails, data breaches, or social engineering. Two-factor authentication adds a second gate: even with your password, an attacker cannot access your account without your phone or authenticator device.
On api228, 2FA is mandatory, not optional. During KYC verification, after you upload your ID and confirm your phone number, our system automatically prompts you to activate 2FA. This ensures that from the moment your account becomes active—and you can deposit funds via QRIS, e-wallets, or bank transfers—your account is secured by two layers of verification.
Users across Indonesian cities—Jakarta, Surabaya, Bandung, Medan, Semarang, and Yogyakarta—benefit equally from this protection. Whether you access api228 on Android or iOS, 2FA operates identically and requires no additional software beyond your phone's native messaging or a free authenticator app.
Types of Two-Factor Authentication
api228 offers two primary 2FA methods. The first is SMS-based authentication: after you log in with your email and password, our system sends a six-digit code to your registered phone number via text message. You enter that code into the login page within ten minutes; if correct, you gain access. SMS 2FA is straightforward and requires no additional app installation—it works on any phone with active mobile service.
The second method is authenticator app-based 2FA. You download a free app such as Google Authenticator, Microsoft Authenticator, or Authy on your phone. During setup, api228 displays a QR code; you scan it with your authenticator app. The app then generates a unique six-digit code that changes every thirty seconds. To log in, you provide your email, password, and the current code from your authenticator app. This method does not rely on SMS and is slightly more secure because the codes are generated locally on your device, not transmitted over networks.
- SMS 2FA
- A six-digit code sent to your phone via text message. Requires active mobile service but no additional software.
- Authenticator App
- A code generated every 30 seconds by a smartphone app. More secure; does not rely on SMS networks.
- Backup codes
- One-time codes provided during 2FA setup. Save these securely in case you lose access to your phone.
- Verification window
- The time allowed to enter a 2FA code. SMS codes typically expire after subject to verification; authenticator codes after 30 seconds.
Setting Up 2FA on api228
After your KYC verification is approved, navigate to your account settings on api228. On Android, open the app, tap your profile icon, and select "Security Settings." On iOS, access the browser version, log in, and find the same menu under Account or Settings. Look for the "Two-Factor Authentication" option. You will see a prompt to choose between SMS or authenticator app.
If you select SMS 2FA, confirm that your registered phone number is correct. api228 sends a test code; enter it to verify. If you select authenticator app 2FA, a QR code appears on screen. Open your chosen authenticator app, tap the plus icon or "Add Account" option, and scan the QR code. The app instantly populates the code sequence. Enter the current six-digit code shown in your authenticator into the api228 setup form to confirm pairing. Once confirmed, api228 displays backup codes—a series of single-use codes that let you regain access if you lose your phone. Write these codes down or store them securely in a separate location.
Saving Backup Codes
Backup codes are a critical safety net. If your phone is lost, stolen, or your authenticator app malfunctions, these codes let you regain account access without waiting for support. Each code is single-use; store all of them in a secure location separate from your phone.
Do not email backup codes to yourself or store them in cloud drives linked to your email account. Instead, write them on paper and store them in a safe place, or use an offline password manager that remains on your computer.
2FA During Deposits and Withdrawals
Once 2FA is active, the security extends to your payment flows. When you deposit via e-wallet, mobile banking, local payment, online payment, e-wallet, or mobile banking, your deposit is processed normally—2FA does not slow deposit processing. However, when you request a withdrawal, api228 requires an additional verification step: after you confirm the withdrawal amount and destination, you must enter your 2FA code. This prevents unauthorized withdrawals even if someone gains temporary access to your login session.
The same applies to large deposits via local payment, online payment, e-wallet, or mobile banking virtual accounts. If you attempt to change your registered withdrawal account or link a new payment method, the system asks for 2FA verification. This layered approach means that even if an attacker learns your password, they cannot move funds out of your account or alter your banking details without your phone.

Troubleshooting 2FA Issues
If you do not receive an SMS code, check that your phone number is correct in your api228 account settings. If you recently changed your phone number, you must update it in your settings before 2FA will work. SMS delivery can occasionally be delayed in regions with poor network infrastructure; wait a few minutes and request a new code if needed.
If your authenticator app code is not accepted, ensure that your phone's system clock is synchronized correctly. Authenticator codes are time-based and will not work if your device's clock is significantly out of sync. Go to your phone's Settings and enable automatic time synchronization. If issues persist, use your backup codes to regain access, then disable and re-enable 2FA to re-pair your authenticator app.
If you lose access to your phone and do not have backup codes, contact api228 customer support. Provide your email, verified phone number, and a clear photo of your ID. Support staff will verify your identity and help you regain access. Response times vary but typically resolve within four hours during business hours. Support is available in Indonesian and English via live chat and email.
