See Help > About Opera to determine the location of your profile folder, though it is generally along the lines of C:\Users\username\AppData\Roaming\Opera Software\Opera Stable\ where username is your username on Windows - and of course change to Opera GX for the latter's profile.

Wait, you're suggesting that there should be an option such as 'Remind me what my passphrase is'? If so, then it's absolutely impossible from the technological point of view - it's not anyone bad will, it's cryptography (pure maths actually). These passphrases aren't actually stored anywhere - they are used to encrypt your data before sending them to Sync servers, and Sync itself has no idea what that passphrase could be. Think of a safe unlocked by a numbers combination - there's no way to know what that combination is just from standing before the safe, unless you completely break it and see what is inside - and this, in case of modern digital encryption, would take a few dozen centuries at least.

@prairiepanda I don't know any.

@LuisAra Moderators help if possible. And this is a forum for users to (try to) help each other, so although people from Opera read it and reply eventually, you should not expect to get reply, technical or not, from them.

@platonio In Opera for desktops, go to the bookmarks manager page and copy the content to the 'Speed Dial' folder. Or to the folder with the name of the device you want.

@parsley If you mean the passphrase, first you need to reset your synced data at sync.opera.com. After that, you go to sync settings in Opera and create a new one. If it's the regular password, just click on the forgot password link on the login page.

Merging similar topics.

@leocg All work fine now. I don't know why but it's ok for me. Thank you

You need to start syncing again to restore your data on the servers.

This is how it was designed to work. Your speed dials from another installation can be seen at other speed dials, your current speed dials won't be automatically changed.

@epop11rt3 Update: I did get Opera Mini to work, but I realized I preferred Edge and Firefox so I uninstalled Opera Mini from my phone.

I don't think they will do it.

@saskiao Hi try this solution, sign on: https://sync.opera.com/web/# best Rafal

+1 -- Meanwhile, you can create a default profile with custom settings and extensions without sync and use it for new installations.
