A resignation can be either verbal or in writing, and is a clear statement by you to your employer that you are going to leave your job. Threatening to leave, or saying that you are looking for another job, isn't the same as formally resigning.
Most companies don't require official written notice before resigning from a position. You can check your employment contract or employee handbook to determine requirements at your specific workplace.

As a part of professional etiquette, you need to write a formal resignation letter when choosing to leave a position.
If you work remotely, resigning by letter is often considered courteous enough. However, if you work in a hybrid or full office setting and have a good relationship with your boss, it is generally better to hand over your resignation letter in person.
