This extension adds a configurable captcha to the backend login after a give amount of failed login tries.
Since TYPO3 Version 11 does have an internal rate limit system, we have decided to abandon the development of this extension for TYPO3 Version 11 and beyond.
- Configurable captcha for backend login
For TYPO3 v10
composer require mfc/mfc-belogin-captcha ^5.0.0
For TYPO3 v9 use the 4.x tags and branch
composer require mfc/mfc-belogin-captcha ^4.1.0
The extensions needs to be configured in the admin tools extensions.
| Name | Description | Default |
|---|---|---|
| failedTries | Failed logins before captcha gets rendered | 5 |
| api_server | reCAPTCHA API-server address | https://www.google.com/recaptcha/api.js |
| verify_server | reCAPTCHA VERIFY-server address | https://www.google.com/recaptcha/api/siteverify |
| public_key | reCAPTCHA public key | |
| private_key | reCAPTCHA private key | |
| lang | reCAPTCHA language |
If no public_key and private_key are set, the configuration of the extension "recaptcha" will be used automatically. When there is no public_key and private_key configured in both extensions, no captcha will be displayed.
