have the same problem

Is there no ETA for this? it can not be so complicated to add the possibility to enter the phrase? Or is it?

This should be fixed as soon as possible! I dont understand why they dont implement such an important feature? Without having the links on my mobile opera is much less an option as other browsers

the problem is:
in opera web you can enter two passwords:

• one for your account and
• one to encrypt your synchronized data

current problem with opera mobile is:

• as soon as you encrypt your synchronized data on web, opera mobile does no longer synchronize any data any longer
  ** reason is probably cause it is not possible to provide the password for the encryption on opera mobile, so it would be good if opera mobile devs would add this
