I'm trying to reset the autofill in the safari browser on my iPhone. Every time I sign into facebook it automatically populated an old email address with an old password. I've gone to settings-->safari-->autofill but there is only an option to turn it on and off, not to edit or clear.
iPhone SE, iOS 10.0.3, null
Try Settings > Safari > Clear History and Website Data
Try Settings > Safari > Clear History and Website Data
If the behavior is exclusive to Facebook, check Settings > Facebook and be certain your old email address does not appear there.
Your response helped me figure it out thanks!
I actually had to go to safari-general-passwords and then delete the old passwords for a bunch of sites 🙂
Thank you, but I tried that too and didn't work :/
Excellent! Glad that solved it.
Enjoy your Apple gear.
