I recently strengthened all my passwords. I used FF on my Mac to accomplish the task and synced the new passwords to Firefox for iOs on my iPhone. I hit the button for autofill passwords, but autofill doesn't work. Often I get a message saying I must have a "passcode-enabled" device. I have that, if they mean the passcode for starting the iPhone after it's been turned off. Wassa matta? Thank you.
