Sorry if this has been done to death. The official TAT site regarding covid vaccination certificates states that they should show nationality and passport or id card number.

The official UK NHS Covid Vaccination Pass shows only name and date of birth. Have there been any reports of people being hassled over this? I doubt that anyone would be so particular now but one would hate to be denied boarding by over-zealous airline staff.

No, not even during the peak of the pandemic - most certificates in the world don't show a passport number or nationality, and many don't even show middle names. Thailand accepted all certificates that appeared genuine, even the handwritten paper cards from the USA.
