While not grammatically wrong, the subject pronoun ‘eu’ is redundant because the verb ending already indicates the speaker.

Cultural Tip
In Brazil people often call the PIN ‘senha’ or ‘senha de 4 dígitos’. When speaking informally you can say ‘esqueci a senha’, but in a formal setting (bank, customer service) the acronym PIN is widely understood. If you’re at an ATM, the machine will usually offer a ‘redefinir senha’ option after verifying your identity.
