how to add your email and phone to the tax portal so you do not get locked out - Elevate Accounting

If you ever get locked out of your Portuguese tax account, having your email and phone number on file can make all the difference. With these details registered, you can reset your password instantly via email instead of waiting weeks for a reset code to arrive by mail—which is sent to your legal address and may even be out of date. This simple update keeps your account access secure and convenient, ensuring you’re never left waiting to get back in. Here’s how to quickly add your email and phone number to the Portuguese tax authority’s website.
