Review login and account-operation records under Security → Account Activity. Some logins may not appear as new entries because of how login tokens work.
Each time you successfully log into your Client Portal (whether through web browser, iOS App, or Android App), a login token is stored on your device. This token remains valid for a specific period, and during this time, your subsequent logins won't be recorded as new entries in the activity log.
Login Token Duration by Device:
Web browsers: 24 hours
iOS and Android apps: 7 days
For example, if you log into the iOS app, the token remains valid for 7 days. Any time you access the app within those 7 days, the token's validity is extended for another 7 days. Only when this token expires and you need to enter your credentials again will a new login record be created.
This is why you might remember logging in but don't see a corresponding record in your account activity log.
To review or remove device access, use Security → My Devices. Check Device, Device ID, Operating System, IP Address, Location and Last Login, then remove any unfamiliar or suspicious device.
