receiving a request for recovering an account of a user of an online service;

establishing at least one video conference session between a client device used by the user, another client device used by at least one trustee associated with the user and a bot agent initiated for the at least one video conference session;

operating the bot agent during the at least one video conference session to guide the at least one trustee to verify an identity of the user;

operating the bot agent during the at least one video conference session to instruct at least one of the user and the at least one trustee, wherein instructing the user comprises instructing the user to perform at least one gesture and/or to pronounce at least one syllable, and wherein instructing the at least one trustee comprises instructing the at least one trustee to request the user to provide at least one real-world information item relating to the user; and

initiating an account recovery process for the account of the user in response to receiving a positive verification verdict from the at least one trustee.

2. The computer implemented method of claim 1 , further comprising verifying the identity of the user by a plurality of trustees associated with the user by:

establishing at least one another video conference session between the client device used by the user, another client device used by at least one another trustee associated with the user and another bot agent,

operating the another bot agent during the at least one another video conference session to guide the at least one another trustee to verify the identity of the user, and

initiating the account recovery process in response to receiving a positive verification verdict from the at least one trustee and from the at least one another trustee.

3. The computer implemented method of claim 1 , wherein the at least one trustee associated with the user is acquainted with the user.

4. The computer implemented method of claim 1 , wherein the user and his associated at least one trustee are members of a common organization.

5. The computer implemented method of claim 1 , wherein the at least one trustee is invited to the at least one video conference session by transmitting at least one message to the at least one trustee via at least one contact channel predefined for the at least one trustee.

6. The computer implemented method of claim 1 , wherein the at least one trustee is admitted into the at least one video conference session after successfully authenticated.

7. The computer implemented method of claim 1 , wherein the guidance provided by the bot agent comprises presenting the claimed identity of the user to the at least one trustee.

8. The computer implemented method of claim 1 , wherein the guidance provided by the bot agent comprises instructing the at least one trustee to verify the identity of the user based on visual appearance of the user.

9. The computer implemented method of claim 8 , further comprising applying at least one liveness verification algorithm configured to determine the user is genuine.

10. The computer implemented method of claim 9 , further comprising operating the bot agent to instruct the user to perform said at least one gesture, said at least one gesture is visually analyzed to verify liveness of the user.

11. The computer implemented method of claim 9 , further comprising operating the bot agent to instruct the user to pronounce the at least one syllable, said at least one syllable is analyzed to verify liveness of the user.

12. The computer implemented method of claim 1 , wherein the guidance provided by the bot agent further comprising instructing the at least one trustee to request the user to provide the at least one real-world information item relating to the user that is used by the at least one trustee to verify the identity of the user.

13. The computer implemented method of claim 1 , further comprising further verifying the identity of the user, in addition to the verification verdict of the at least one trustee, based on at least one biometric pattern of the user captured during the at least one video conference session compared to a respective biometric signature recorded in the account of the user, the at least one biometric pattern is a member of a group consisting of: a face pattern, an iris pattern, a voice pattern and a fingerprint pattern.

14. The computer implemented method of claim 1 , wherein the account recovery process is initiated by transmitting to the client device used by the user a one-time use link to a recovery site.

15. The computer implemented method of claim 14 , further comprising transmitting a unique secret assigned to the account recovery process to the client device used by the user, the unique secret is provided via the client device when accessing the recovery site.

16. A system for recovering an account of a user based on verification of the user in a video conference, comprising:

at least one processor configured to execute a code, the code comprising:

code instructions to receive a request for recovering an account of a user of an online service;

code instructions to establish at least one video conference session between a client device used by the user, another client device used by at least one trustee associated with the user and a bot agent initiated for the at least one video conference session;

code instructions to operate the bot agent during the at least one video conference session to guide the at least one trustee to verify an identity of the user;

code instructions to operate the bot agent during the at least one video conference session to instruct at least one of the user and the at least one trustee, wherein instructing the user comprises instructing the user to perform at least one gesture and/or to pronounce at least one syllable, and wherein instructing the at least one trustee comprises instructing the at least one trustee to request the user to provide at least one real-world information item relating to the user; and

code instructions to initiate an account recovery process for the account of the user in response to receiving a positive verification verdict from the at least one trustee.

A computer program product for recovering an account of a user based on verification of the user in a video conference, comprising a non-transitory medium storing thereon computer program instructions which, when executed by at least one hardware processor, cause the at least one hardware processor to:

receive a request for recovering an account of a user of an online service;

establish at least one video conference session between a client device used by the user, another client device used by at least one trustee associated with the user and a bot agent initiated for the at least one video conference session;

operate the bot agent during the at least one video conference session to guide the at least one trustee to verify an identity of the user;

operate the bot agent during the at least one video conference session to instruct at least one of the user and the at least one trustee, wherein instructing the user comprises instructing the user to perform at least one gesture and/or to pronounce at least one syllable, and wherein instructing the at least one trustee comprises instructing the at least one trustee to request the user to provide at least one real-world information item relating to the user; and
