@leocg Thanks for the answer.

Yes, passwords are securely stored on Opera servers. I do not doubt it.

But if anyone gets access to my Opera account. He can easily get my passwords too.

That is, the Opera account itself is not secure enough? If there was an authentication via SMS or Email, it would be more secure.

Hello!

I have a question about synchronization security in Opera.

Is it possible to configure two-step authentication for synchronization?

As I understand it, this can not be done. Is it safe to save passwords in Opera account, without two-factor authentication?

For example, Google Chrome, Mozilla Firefox, or Microsoft must ask for confirmation (via E-mail, SMS, etc.).
