People who sleep better.
"Switched from 1Password and never looked back. The UI is cleaner, the price is better, and the breach alerts have already saved me twice."
"I set it up for my entire family. Now my mum stops texting me 'what's the Netflix password.' That alone is worth every penny."
"Zero-knowledge architecture was the dealbreaker for me. I work in fintech — I can't afford to trust a company that CAN read my data."
