Yes, everyone should be using unique passwords. Yes, people should not share information that they would not want unintended viewers to see. Yes, if people have a problem with its security practices they can move to other apps. Do these (false) assumptions of the userbase mean the implementation of proper safeguarding practices should be ignored? Absolutely not.

Grindr serves an incredibly vulnerable population. Since it is by the most popular platform for this population, it is its responsibility to do what is most ethically and morally responsible, even if it makes people slightly awkward when logging in.

Our personal information is only as secure as the peoples' accounts that we share that information with. I can setup complicated passwords for this one app, but if an account that I have interacted with becomes compromised because they did not take the same steps as I did, then everything I shared is also compromised.

We can't make the assumption that even a majority of users make their Grindr password unique. Thus, it ought to be mandatory for Grindr users to participate in 2-Factor Authentication. This will not completely solve the problem of data security and digital safety, and it also would not be a popular change, but it would be a major step in protecting the safety and security of its userbase.
