If set, allows only the set number of IPs to access the lockbox account. These days people
have different IP addresses, but also share login details with friends. This useful security option can help
prevent multiple logins from the one account. Max 99999.
It's worth considering the fact that many people have laptops, tablets and phones these days and log in from work
and home locations. Also people without fixed IP addresses will have a different IP should they restart their router. You should factor this into your limit.
If you set a limit of 1, the login IP must always be the same as the signup IP. This is the strictest setting.
Set to 0 to disable. Note that there are no restrictions for the master login credentials. You can also set different
values for different members via the
member override option.
NOTE: To clear existing IP addresses, delete the corresponding login events for a member.
IMPORTANT: For this feature to work, 'login' events MUST be enabled in the members
event log.
