Τι είναι το OAuth; It is very likely that you have allowed some applications ή ιστοσελίδες να έχουν πρόσβαση στους λογαριασμούς σας στην Google, Facebook, Twitter, Dropbox, ή την Microsoft. In every application once you have granted access, you should know that it will continue to have it until you revoke it.
In other words, there are probably several other online services that have access to your personal data. So you should regularly check the lists of services that link to your webpages and remove the services you do not use anymore.
Why do these third-party services have access to your accounts?
When you use an app or web service that requires access to an account - for example, in your Google Account, the app generally does not ask you to use a password to access the service. Instead, it uses something called OAuth. If you agree to the prompt, the app will gain access to your account and in doing so will give you a kind of authentication. So the site you want to use without making a new record will give you a token that you can use instead of a password to access your account.
When you give access to an application, you will see a window asking for your permission to access your Google account, for example.
So far, everything is fine. The problem is that we can easily forget which apps and services have access to your account. You can try an application for once and never use it again, or you may have stopped using an app years ago. If you have not checked the list of approved apps and removed it from there, this app still has access. It is well known that we have mentioned in other publications that many applications can use their access to collect data without your permission.
Changing your password will not revoke access to these linked apps. Even if you change all of your passwords. the services that access your account will retain access.
So how can you un-access the applications you do not use?
Use the links below
To secure your bills, you should visit a special page on each web page you use to check the list of linked services. If you see a service or an application that you are not using, immediately recall access.
To make it easier, we've collected a list of the most popular websites that use OAuth. You simply click on the link you are interested in to check the list of connected services.
It should be noted that, it is not the best idea to click on links that ask to have access to your Google, Microsoft, Facebook or Twitter accounts to log in with your password. Phishers can mimic sites to steal your passwords.
