How sidni Two-Factor Authentication Works
When you enable 2FA on sidni, your account requires two pieces of information to unlock: your password and a second proof of identity. That proof arrives as a time-limited code via SMS, an authenticator app like Google Authenticator, or an email link. Even if someone obtains your password, they cannot access your sidni account without that second factor.
Our system generates a fresh code every 30 seconds on authenticator apps, and SMS codes expire after five minutes. This window is long enough for you to copy and paste the code during login, but short enough to prevent brute-force attacks. On sidni, we do not log your 2FA codes; each verification is stateless, meaning no record of your code lingers on our servers.
sidni 2FA Methods
We offer three authentication channels on sidni. SMS codes are the quickest for users who do not want to install a separate app; they arrive within seconds to your registered phone number. Authenticator apps — Google Authenticator, Microsoft Authenticator, or Authy — give you offline access to codes, which is useful if your phone has limited signal during a match in Jakarta or Bandung.
Email-based verification is our third option, commonly used for withdrawals or sensitive account changes. When you request a withdrawal via DANA, e-wallet, or mobile banking, sidni may prompt you to confirm the transaction through an email link, adding a layer of proof that you initiated the action.
Setting Up Two-Factor Authentication on Android
Opening the sidni Android app and navigating to your account settings is the starting point. Look for the "Security" or "Account Protection" menu. On most Android devices, this is under your profile icon in the top-right corner, then Settings → Security.

Save backup codesSetup step 4
sidni generates one-time backup codes. Store these safely (e.g., in a locked notes app or printed envelope). Use them only if you lose access to your 2FA method.
Backup codes are single-use and cannot be reused
Once you enter a backup code to regain access to sidni, that code is consumed. Keep your list safe and do not share it with anyone.
Two-Factor Authentication on iOS Browser
If you use Safari or another iOS browser to log into sidni, the 2FA flow is identical. After entering your email and password, you will see a prompt asking for your 2FA code. Open your authenticator app, SMS, or email — whichever method you enabled — and copy the code into the login screen.
On iOS, we recommend storing your authenticator in a place you access frequently. Many users keep Google Authenticator or Authy on their home screen, just like our sidni app icon. This way, when you log in during a Liga 1 match or while watching Piala AFF highlights, the extra step takes only a few seconds.
Payment Verification and 2FA
When you initiate a withdrawal on sidni — whether through local payment, online payment, e-wallet, mobile banking, local payment, or your bank account (online payment, e-wallet, mobile banking, local payment) — we may request additional 2FA confirmation. This extra step prevents unauthorized withdrawal requests.
Our payment-processing window typically includes a verification check. After you request a payout, sidni sends a code to your registered contact method. Only after you confirm that code does the withdrawal proceed through our payment partner. This protects your balance against account takeover.

- sidni supports SMS, authenticator apps, and email-based verification
- Backup codes are one-time recovery tools; store them securely
- Payment withdrawals often require separate 2FA confirmation for extra safety
- Setup takes under five minutes on Android or iOS browser
Managing Your 2FA on sidni
After you activate 2FA, sidni lets you change methods at any time. If you switch phones, lose your device, or want to replace your authenticator app, visit your security settings and select a new 2FA channel. The process mirrors the initial setup: verify your contact, enter a test code, and confirm.
If you have already saved backup codes, you can use one of them to regain access if you lose your 2FA device. Log in with your email and password, then when prompted for 2FA, select "Use backup code" and enter one of your saved codes. sidni marks that code as used so it cannot be reused.
Our support team can assist if you are locked out. Contact us via the Help menu in your sidni app or browser. We verify your identity using account details (email, registered phone, recent transactions) and help you restore access. This verification process may take a few hours, so if possible, keeping your backup codes accessible is faster.
