Generate a Random String

The Generate a Random String action generates a random string of characters. Configure which character sets to include and how long the result should be.

When to Use This Action

Use this action when:

• You need a unique token, temporary password, or random identifier
• You want a configurable mix of character types (letters, numbers, symbols)
• You need a value that is unique for each workflow execution
