Identify both sides of the connection
Record the vehicle model and year along with the current or proposed opener model. A button built into the car does not establish that it will work with every garage operator. Ask for the supported combination to be checked before making it a purchase requirement.
Include accessories in the comparison
If an additional compatible component is proposed, have it named and priced in the quote. Compare that complete setup with the other options you are considering. Otherwise a lower opener price can conceal a separate accessory needed for the control you use most.
Plan the handover around authorized users
Discuss which vehicles should be included in the setup and whether their owners need to be present. Keep the instructions for later changes. If a vehicle is sold or a control is lost, ask how access should be updated for the installed equipment.
Your questions
Can the logo on the opener prove compatibility?
No. The exact model and supported control system matter. Broad brand matching is not enough to confirm every feature.
Should I share my car or account credentials in the request form?
Provide ordinary model information first. Handle any necessary access credentials privately during the authorized setup process.
