I saw a topic that looked like mine but not exactly the same.
So i lost access to all my passwords on opera sync because i just changed the password of my opera account after reinstalling my OS. I don't know if there is a way to get them back, I just know how many i lost of it which is kinda sad.
Thank you for the future replies.

@leocg yes it asks me my old password but i just lost it. Also it's the first time i hear about the passphrase. For now i did not reset but it's my only option i guess. It sucks. Thank you for the replies
