Learn Farsi: من حساب خود را به‌روزرسانی کرده‌ام.

The infinitive is به‌روزرسانی کردن (to update). To form the present perfect ("have updated"), the non-verbal part (به‌روزرسانی) stays exactly the same. Then, we take the verb کردن (to do/make), turn it into its past participle (کرده), and attach the present perfect ending for "I" (ام).

What are the parts that make up the word به‌روزرسانی?

It literally means "bringing to the day" or "bringing up to date." It is built from به (to), روز (day), and رسانی (bringing/delivering). You will see this word often for software, app, or account updates!

Why does the sentence use حساب خود instead of just حسابم for "my account"?

Both are correct and mean "my account." However, using the word خود (self) to make حساب خود translates closer to "my own account." It sounds a bit more formal or official, which fits perfectly when talking about updating a system or bank account.

Why does the direct object marker را come after خود?

The word را always goes at the very end of the entire phrase that is receiving the action. Since the complete direct object here is حساب خود (my account), the را waits until after the word خود to appear.
