# Access Codes in Cadmus Exams
## Learn how to enable, generate, customise, and manage access codes for Cadmus exams.
Access codes are unique entry codes that help teachers control student access to exams and support academic integrity. When access codes are enabled, students must enter a valid code before they can begin their exam.

#### Enabling access codes
The **Access Code** requirement setting can be enabled from the *requirements and settings* page in Cadmus, under the **Assessment Integrity** section.
When access codes are enabled, one code is automatically generated.
#### Generating and managing access codes
To create additional codes, click the **Generate More** button. By default, generated codes will use labels such as Exam Code 1, Exam Code 2, and so on.
You can also:
- Copy a single code using the **Copy** icon beside each code
- Click **Copy all codes** to copy every code at once
- Rename the label to help identify different codes easily
- Customise a code by clicking into a letter box and typing to replace it
**Note**: All Access Codes are 6 characters long and accept alphanumeric characters only.
#### Customising access codes
Teachers can customise automatically generated access codes to suit their exam arrangements.
For example, if an access code has already been shared with invigilators, teachers can update the generated code to match the code they intend to use.
To customise an access code:
1. Locate the access code under **Assessment Integrity** in the exam settings.
2. Click into the character box you want to change.
3. Replace the existing character with your preferred letter or number.
4. Repeat for any other characters you wish to change.
****
**Note:** Custom Access codes must contain exactly six characters and can only include letters and numbers.
#### Student experience
When students open the exam link from their LMS, they will see a pop-up asking them to enter an access code before they can begin the assessment.
#### Viewing access code usage
Any access codes used by a student will appear in:
- *Progress* tab
- *Learning Assurance* tab
- Sessions log within the Activity Report
