Uh no. First off, I'm not on the free tier. I'm not on the most expensive tier, but I do pay for my account $4.99 monthly. Second, I used the built in features exactly as intended. Every login entree in Proton Pass has the option to add additional fields that you can name. That's what I did, every security question being the name, and every answer being the data filled in. There was nothing to circumvent, because at least according to their pricing plans, even the free tier claims to allow unlimited logins.
It is literally ransomware. They allowed me to enter data in their program as intended, and then held that data ransom in order to pressure me into upgrading into a higher tier.
