The details that sign you into the prop firm's website are rejected by the trading platform.
The firm's client area and the trading platform are separate systems with separate credentials. Buying an account creates a platform login that is issued to you separately.
The dashboard handles your purchase, your evaluation progress and your payouts. The platform holds the trading account. They are joined by the firm's internal process, not by a shared password, so a reset in one place has no effect on the other.
If you hold more than one account with the firm, each one may have its own platform login, which is why details that worked last month can fail on a new account.
You reach the trading interface and the balance matches the figure on your dashboard for that account number.
Store dashboard and platform credentials as separate password manager entries, tagged with the account number, and add a new entry for each new account rather than editing the old one.
