A behavior to keep using technology can be seen from the attitude of attention to information technology. Behavior is a form of will, that is, willing to keep using, willing to add supporting features, as well as to be influenced to motivate others to use the technology. A successful implementation of information technology can be seen by paying attention to the behavior of the user. The PT. TASPEN (PERSERO), one of the state-owned enterprises engaging in non-banking finance, has digitized its services since 2017, one of which is by utilizing technology in terms of providing easiness for the participants, namely the participants of Taspen Pension who try to change the paradigm of withdrawing their monthly retirement salaries, which is from manual to digital. This study aims to determine the phenomenon of utilizing the technology established by Taspen to simplify retirees through behavioral intention influenced by several factors: performance expectancy, effort expectancy, social influence, trust, and facilitating conditions; to get an actual system use from the service digitalization established, i.e., the Taspen authentication system. The respondents to be addressed are the participants of Taspen Pension within the JABODETABEK area, whether they have used the Taspen authentication system or vice versa.
