If this supports OTP, and ideally profiles, I'd likely cancel my 1Password subscription. I've been waiting for Apple to release something like this for a long time and surprised it took them this long.
Keychain has been built into all apple devices for ages, and all support OTP and seamless sharing across all your devices. Genuinely interested to know why you have been using 1Password when apple will already do it all for you? Did you not know?
iOS already supports OTP, it’s just buried in Settings > Passwords > Set up verification code. Once you do that, it’s seamless - it autofills in all my site and works beautifully in chrome/edge/firefox even in my PCs
