Stop Storing Third-Party Tokens in Your Database
Auth0 Token Vault handles secure token storage, exchange, and refresh for external providers so you don't have to build it yourself.
Rolling your own OAuth token storage can be a security liability. Token Vault securely stores access and refresh tokens from federated providers and handles exchange and renewal automatically. Connected accounts, refresh exchange, and privileged worker flows included.
There are Captcha exchange services like 9kw.eu or Capcha Brotherhood that let you collect points by solving Captchas of other users. You can spend these points for letting someone else solve your Captchas, e.g. in download managers.
