It is opera one, had to create a new login for gas safe register site as they are now using 2 step verification, i know i had a similar problem before with the password auto creating but managed to turn it off on a previous version of opera last year but couldnt find any option to do so this time.

Opera has updated on my windows 10 64 bit laptop and now wants to auto fill any passwords, im unable to type over the top of these. i have tried to cancel the auto fill, but cannot find an option the only thing that stopped it is to cancel the save password option which i want to keep.
