Security
What actually stops someone
Most of what a bank calls security is a screen that hides a button. Here is what happens underneath, where hiding a button changes nothing.
The database refuses, not the code
A negative balance, a second main account, an active card that was never approved: the engine turns them down. Not a condition somebody could forget to write.
- Closing gives the money back first
- Refused by the database
- The main account
- One per client
- Cards
- Approved before being active
Nothing is deleted quietly
An audit line names who acted, when, and from where, and it cannot be erased by the person it names — the database refuses that too.
The receipt of a transfer, exactly as the portal issues it.

Security
A sign-in that really locks
Five wrong attempts lock the sign-in, and during the lock even the right password is refused. A counter you can outrun is no counter.
- Five attempts, then a quarter-hour lock — and during that lock the right password is refused too.
- Every attempt is written to the log, successful or not.
- Two-factor authentication is available, and turning it off is guarded like turning it on.
- The full number and the security code are fetched only when you ask, are never part of the page’s state, and every reveal is written to the audit trail.
Protected sign-in
A lock after five tries, two-factor authentication on top, and every attempt traced.
