First Security Islami Bank / Sammilito Islami Bank ❤️ Log In

First Security Islami Bank Log In now sits inside a major banking transition. Bangladesh Bank says five Shariah-based banks, including First Security Islami Bank, were merged into the new state-owned Sammilito Islami Bank PLC, which became a scheduled bank on December 1, 2025.

Legacy FSIB services and support pages are still online, including iBanking and FSIB Cloud. Do not assume that every customer, account or transaction has already moved to a new digital channel. Confirm the current servicing route with the branch or verified 24-hour call center before entering credentials, moving money or responding to a migration message.

Bangladesh Bank’s current monetary-policy review states that the resolution framework for five Shariah-based banks led to their merger into Sammilito Islami Bank PLC. The new bank was enlisted as a scheduled bank on December 1, 2025. First Security Islami Bank was one of the five institutions involved.

A legal merger does not prove that a particular login, card, branch record or payment instruction changed on the same day. Use the newest formal notice for the specific account. If an old FSIB service still opens, verify the account and current servicing instructions before treating it as final evidence that no migration applies.

1. Keep the newest account and merger notices.
2. Match the account number or ending before acting.
3. Ask the branch which legal bank now services the account.
4. Confirm whether the existing FSIB username remains valid.
5. Do not create a second profile from an unsolicited message.
6. Verify any new payment or beneficiary instruction independently.
7. Escalate missing funds or records through a documented complaint.

The legacy FSIB iBanking registration form says the service is linked to all accounts under the customer’s Customer ID. It asks the customer to submit a branch-verified application, and the bank assigns an iBanking user ID. The older process used a temporary password delivered to the registered email and required a change at first login.

If access existed before the merger process, do not submit a new application merely because a saved password fails. First verify the user ID, registered email and phone, lock status and current servicing bank. A branch may need to update identity details or reissue access.

1. Use a branch-verified registration process for first-time iBanking.
2. Confirm the Customer ID and linked accounts.
3. Receive credentials only through the bank’s established process.
4. Change a temporary password at the verified first login.
5. Recover or unlock an existing user instead of creating duplicates.
6. Update an unavailable email or phone through the bank.
7. Confirm which access rules remain after the merger.

FSIB currently describes Cloud transfers between own and other FSIB accounts and transfers to other banks through BEFTN and RTGS. It also describes utility payments, QR merchant payments and mobile recharge. Transfer actions may require a T-PIN and two-factor authentication.

Before sending money, verify the legal servicing bank, source account, beneficiary, amount, channel and any migration restriction. Submit once, save the reference and wait for a clear accepted, pending, rejected or completed status. Do not repeat an instruction solely because a screen refreshed slowly.

1. Confirm the source account and available balance.
2. Verify beneficiary name, number and receiving bank.
3. Check whether BEFTN or RTGS is appropriate.
4. Approve only a T-PIN or code for your own transaction.
5. Save the transaction reference and time.
6. Check both account histories before retrying.
7. Ask the bank to trace a delayed or duplicated transfer.

A customer in a bank-resolution transition should preserve statements, deposit certificates, transaction references and formal notices. Compare the newest balance and account title with the last reliable statement. A missing product can be a migration or account-linking issue rather than a simple password failure.

FSIB still publishes a central complaint channel and complaint-management cell. Use a written complaint when a branch or digital channel cannot explain a missing balance, blocked access, unrecognized transaction or changed servicing instruction. Keep the complaint reference and every written response.

1. Download or retain current statements when access works.
2. Keep deposit and investment documents securely.
3. Record the last known correct balance and date.
4. Write down the exact missing account or transaction.
5. Open a documented complaint when ordinary support fails.
6. Keep the complaint number and response deadline.
7. Escalate unresolved material discrepancies through current official channels.
