@jihan2011 I just figured it out on mac,
- search for keychain access
- find Opera Safe Storage
- under access control allow all applications
- open Chrome Safe Storage
- under access control allow all applications
5.restart both browsers and log in - click your log in letter/account on the top right of opera browser
- there should be first option sync syncronization
- click sync, sync everything, choose chrome
- Wallah!After that i wont go back and change those setting to not allow all applications just incase for safety so no sketchy applications get your password bank
