Hello, do I need to rent a highway pass when renting a car? I've heard that Portugal's highway tolls are complicated ?

We recommend using Easytoll to bind credit cards for payment. You will be charged the amount you drive, plus an initial fee of 0.6 euros + VAT, and an additional 0.26 euros + VAT per journey. This payment method is only suitable for vehicles entering Portugal from Spain on the A28, A24, A25 or A22 highways, and is not suitable for tourists entering Portugal from grey roads or other free roads and encountering red electronic toll sections. When using this method, remember to unbind your credit card on the http://www.portugaltolls.com website after leaving Portugal, otherwise someone else's car may be charged to your credit card within a month. When driving from Salamanca to Porto, we drove on the A25 highway. After crossing the border, we slowed down and drove to a BP gas station. The EasyToll self-service registration station is in the middle of the highway, and you need to reverse left at the entrance in front of the gas station, and then follow the arrow to turn right to reach it.
