慈濟系統登入工具 is a new and innovative login system and authentication tool developed by the Buddhist Tzu Chi Foundation. This app requires users to input their personal Tzu Chi account (LDAP account) and the phone number registered with the Tzu Chi Foundation system in order to register and use the app.

To find your Tzu Chi account, please contact your local religious or financial department personnel. Members can also find their Tzu Chi account (LDAP account) through the path set up in their own electronic fundraising book.

To update your personal phone number in the Tzu Chi Foundation system, please contact your community personnel officer or personnel from the local religious or financial department.

It's important to note that this app can only be installed on one device at a time. Installing it on a new device will overwrite the previous installation, so users should exercise caution when changing phones or phone numbers.
