What is claimed is:1. An electronic device comprising:a display;a sensor configured to obtain a biometric information of a user;a memory configured to store at least one instruction; andat least one processor configured to execute the at least one instruction to:based on an event related to executing an application, identify execution of biometric authentication associated with the application;based on the identification, output information corresponding to the biometric authentication to be performed in the electronic device;obtain, by the sensor, the biometric information of the user;identify authority using the obtained biometric information and registered biometric information stored in the memory; anddisplay, by the display, a screen associated with the executed application based on the identified authority.2. The electronic device of claim 1, wherein the application is an application in which the user is predesignated.3. The electronic device of claim 1, wherein the information corresponding to the biometric authentication comprises a type of the biometric authentication.4. The electronic device of claim 1, wherein the information corresponding to the biometric authentication comprises a capturing angle of the sensor with respect to the user.5. The electronic device of claim 4, the at least one processor is further configured to execute the at least one instruction to:receive a user input; andmodify the capturing angle of the sensor in response to the user input.6. The electronic device of claim 1, wherein the biometric authentication comprises at least one of vein authentication or iris authentication.7. The electronic device of claim 1, the at least one processor is further configured to execute the at least one instruction to:display a process of capturing and generating at least one of image based on the biometric information.8. The electronic device of claim 7, the at least one processor is further configured to execute the at least one instruction to:display an image of cross-comparing the image based on the biometric information with an image based on the registered biometric information.9. The electronic device of claim 1, wherein the event comprises receiving a user input, by an input unit, in order to execute the application.10. The electronic device of claim 1,wherein the at least one processor is further configured to execute the at least one instruction to:display, on a body of the user, an authentication region using a light module.11. A method of operating an electronic device, the method comprising:based on an event related to executing an application, identifying execution of biometric authentication associated with the application;based on the identification, output information corresponding to the biometric authentication to be performed in the electronic device;obtaining, by a sensor, the biometric information of a user;identifying authority using the obtained biometric information and registered biometric information stored in a memory; anddisplaying, a screen associated with the executed application based on the identified authority.12. The method of claim 11, wherein the application is an application in which the user is predesignated.13. The method of claim 11, wherein the information corresponding to the biometric authentication comprises a type of the biometric authentication.14. The method of claim 11, wherein the information corresponding to the biometric authentication comprises a capturing angle of the sensor with respect to the user.15. The method of claim 14, further comprising:receiving a user input; andmodifying the capturing angle of the sensor in response to the user input.16. The method of claim 11, wherein the biometric authentication comprises at least one of vein authentication or iris authentication.17. The method of claim 11, further comprising displaying a process of capturing and generating at least one of image based on the biometric information.18. The method of claim 17, further comprising displaying an image of cross-comparing the image based on the biometric information with an image based on the registered biometric information.19. The method of claim 11, wherein the event comprises receiving a user input, by an input unit, in order to execute the application.20. The method of claim 11, further comprising displaying, on a body of the user, an authentication region using a light module.
