09Frequently asked questions
Can I reinstall to reset it?
A reinstall keeps the database if you do not delete it, but the login may remain. Ask first.
Is there a default password?
Older versions may use defaults; do not rely on it.
Will I lose attendance data?
Not if you keep the database.
Is it the same as the terminal password?
No.
