Migrate to reCaptcha enterprise

[liangyuanruo]

We have exceeded the free limits for recaptcha, and must migrate to the enterprise version within 30 days.

reCAPTCHA Developer -

We are writing to inform you that your site is currently using reCAPTCHA  
over the quota limit (1M Calls Per Month or 1K Calls Per Second).  Limits  
will be enforced 30 days following this notice.

If you wish to make more than 1,000 calls per second or 1,000,000 calls per  
month, you must use reCAPTCHA Enterprise. If a site key exceeds 1000 QPS  
requests, then some requests may not be processed. If a v3 site key exceeds  
its monthly quota, then site_verify may fail open by returning a static  
score 0.9 and an error message `"Over free quota."` for the remainder of  
the month. If a v2 site key exceeds its monthly quota, then the following  
or a similar message may be displayed to users in the reCAPTCHA widget for  
the remainder of the month: `This site is exceeding reCAPTCHA quota.`

If your business needs to continue using reCAPTCHA over this rate,  
reCAPTCHA Enterprise  
(https://cloud.google.com/recaptcha-enterprise/docs/migrate-recaptcha) is  
available with unlimited quotas and support.

If you have any questions or would like us to connect you with our customer  
engineering team please let us know at

Do not reply to this email.

Thanks,
reCAPTCHA Team

Migration complete on 3 Aug 2021 Do note that as we are using v2:

• Need to maintain both v2 admin and enterprise console. Do not delete the keys on either side
• Captcha difficulty can be configured on v2 admin console
