One option is to lock out the passwords for some amount of time, or to do geolocation.
Both can be defeated (they can detain you at the airport for a whole day, or they can spoof GPS) but neither of these mechanisms holds up to mass surveillance: you can't detain everyone who goes through the airport, or even all people with 1Password, for a day, nor can you spoof GPS at the security checkpoint because it'll probably leak to airplanes. You have to pick individual travellers and put them in a Faraday cage with a Stingray and an internet connection.
I'm not sure what the threat model really is, but it's possible that this will require enough time and resources to disincentivize asking for even more passwords when there's not a very specific suspicion, which might be good enough.
