The CCUES of Société Générale offers each year a catalog of stays at preferential rates, open to active employees, their dependents, and retirees of the group. For the 2026 season, registrations for spring, summer, and autumn stays cover the period from March 28 to October 31. Access to the catalog and reservations are exclusively through the portal csec-sg.net, with technical constraints that are better anticipated.
Two-factor authentication and network blocking: what the CSEC SG portal imposes in 2026
Since 2025, the portal csec-sg.net operates with two-factor authentication. After entering the password, an additional code is sent via email or to the phone. This mechanism extends the connection by a few seconds, but more importantly, it requires immediate access to one’s personal email or mobile at the time of booking.

The other constraint, less intuitive: connection from a Société Générale workstation is blocked. The company’s internal network prevents any access to the CSEC site. Employees must therefore use a personal device (computer, tablet, smartphone) connected to a home or mobile network.
This restriction poses a concrete problem during registration openings, where spots fill up quickly. To prepare, it is better to set up your session the day before by checking your credentials and testing the reception of the authentication code. An employee who discovers an expired password on the day of the reservation opening risks missing out on the most sought-after destinations. All information on the CCUES SG 2026 vacation catalog helps to prepare in advance.

Registration during red period: calendar and summer discount 2026
The catalog distinguishes two phases of registration. The red period operates on a priority system, with a fixed deadline. For summer 2026, requests submitted before the end of the red period are processed as a priority. Beyond that, applications are examined in the order they are received, without any guarantee of availability.
The summer stays for 2026 are divided into modules of fifteen days:
- From July 4 to July 18
- From July 18 to August 1
- From August 1 to August 15
- From August 15 to August 29
Registration for the week remains possible, but without priority compared to reservations for a complete module. A price advantage applies to the first week (from July 4 to July 11) in the form of a discount, excluding accommodation and extensions.
Strategy for choosing dates
The modules at the beginning and end of the season are often less in demand. Choosing the module from July 4 to July 18 or from August 15 to August 29 increases the chances of obtaining the desired destination while benefiting from more advantageous rates on certain stays.
Outside the red period, remaining spots are allocated on a rolling basis. This means that an application sent a few days after the closure of the priority period can still succeed, depending on the occupancy rate of the targeted destination.
Retiree access to the CCUES SG catalog: a distinct profile to maintain
Retirees of Société Générale retain access to the vacation catalog, but through a retiree profile separate from their former employee account. This profile requires a specific identifier, which must be activated or maintained over time. Confusion between the old professional identifier and the new retiree profile is a frequent source of blockage.
The critical point concerns the email address. The portal requires a unique and valid personal email address for any account management operation: password reset, receipt of the two-factor authentication code, booking confirmation. If the registered address is outdated, full, or inaccessible, no recovery mechanism will work.
Checks to perform before the opening of registrations
- Check that the email address linked to the retiree profile is indeed the one used daily
- Test a complete connection (password and authentication code) several days before the opening date
- In case of problems, contact the family vacation service at 01 42 14 30 67 or by email ([email protected]) before the influx of requests
Children and adolescents stays: separate catalogs not to be confused
The CSEC SG publishes separate catalogs for adult and family vacations on one side, and for children and adolescents stays on the other. The two types of stays are not booked in the same section of the portal and follow different registration calendars.
For children’s stays, the dedicated contact is the colonies service (01 42 14 48 80, [email protected]). Family stays fall under another service. Sending a request to the wrong contact delays the processing of the application, sometimes beyond the priority registration window.
The winter-spring 2026 catalog for children and adolescents covers stays organized during school holidays, with specific programs by age group. Parents must check the age group corresponding to their child before booking, as an age mismatch with the stay dates may lead to a refusal of registration.
The management of the CCUES SG vacation catalog relies on precise technical and calendar constraints. An up-to-date account, a functional email address, and registration as soon as the red period opens remain the three most reliable levers for accessing the desired stays in 2026.
