How to set the Login hours and Login IP ranges to the users in Salesforce?

Hi Avnish,

Login hours- If Login hours set in an organization, then it restricts to log in before or after login hours.
Setup | Administration | Manage users | Profiles.
Login IP – It helps to restrict the unauthorized IP addresses login attempt.
Setup | Administration setup | Manage users | Profiles.

Hi,

To add more into this -

• How you restrict the range of valid IP addresses on a profile depends on your Salesforce edition.
  • If you’re using an Enterprise, Unlimited, Performance, or Developer Edition, from Setup, enter Profiles in the Quick Find box, then select Profiles, and select a profile.
  • If you’re using a Group, or Personal Edition, from Setup, enter Session Settings in the Quick Find box, then selectSession Settings.
  • In a Professional Edition, the location of IP ranges depends on whether you have the "Edit Profiles & Page Layouts" org preference enabled as an add-on feature.With the "Edit Profiles & Page Layouts" org preference enabled, IP ranges are on individual profiles.Without the "Edit Profiles & Page Layouts" org preference enabled, IP ranges are on the Session Settings page.
• Click New in the Login IP Ranges related list.
• Enter a valid IP address in the IP Start Address field and a higher-numbered IP address in the IP End Address field.The start and end addresses define the range of allowable IP addresses from which users can log in. To allow logins from a single IP address, enter the same address in both fields.
  • The IP addresses in a range must be either IPv4 or IPv6. In ranges, IPv4 addresses exist in the IPv4-mapped IPv6 address space ::ffff:0:0 to ::ffff:ffff:ffff, where ::ffff:0:0 is 0.0.0.0 and ::ffff:ffff:ffff is 255.255.255.255. A range can’t include IP addresses both inside and outside of the IPv4-mapped IPv6 address space. Ranges like 255.255.255.255 to ::1:0:0:0 or :: to ::1:0:0:0 aren’t allowed.
  • Partner User profiles are limited to five IP addresses. To increase this limit, contact Salesforce.
• Optionally enter a description for the range. If you maintain multiple ranges, use the Description field to provide details, such as which part of your network corresponds to this range.
• Click Save

Hope this helps.
