Configures email-based one-time passcode (OTP) two-factor authentication. A code is emailed to the user at login and must be entered to proceed.
Settings
- Code Length
- The number of digits in the one-time code. Must be between 4 and 16. Default is 6. Longer codes are more secure but harder to type.
- Use Cloud Service
- When enabled (default), email codes are sent via the platform's hosted cloud email service. Disable to use the locally configured SMTP server instead.
- Prompt For Emails
- When enabled, users who do not have an email address on their profile are prompted to enter one before the code is sent.
- Minimum Emails Required
- The minimum number of verified email addresses a user must have registered before email authentication can be used. Range 0–10; default 1.
When "Use Cloud Service" is disabled, ensure that an SMTP server is configured and working before enabling this authentication method.
