Inform Direct no longer stores passwords. Sign-in is managed by BrightID, so there is no Change password option in Inform Direct.
To change your password:
1. Go to hub.brightsg.com. You are signed in automatically if you are logged in with your BrightID.
2. Select your initials in the top-right corner, then click Edit Profile.
3. Go to the Security section and change your password there.
If you have forgotten your password, see How Do I Get a New Password If I Have Forgotten It?
