Logging in via E-Mail

• Enter your E-Mail.
• You get an E-Mail which has a link in it
• Click on the link (or copy it into the address bar of your browser and open the link)
• Click on "Login"
• Now open the service you want to use again. You are now automatically logged in.
• In future you can use this link again to login
• If you send yourself a new link, this expires the previous one within 5 minutes
• If you click "Logout", this expires the link. Sometimes the link expires for different other reasons as well.
• In that case you see the login page again, and depending on the "remember" setting you see your E-Mail address again and can quickly send yourself another authorization E-Mail
• Note that your E-Mail address is kept in an encrypted Cookie in your browser, not on our side!
• Do not use the "remember" setting if you are not on your own computer. However there is no much harm done, except that perhaps some of your privacy data leaks to others of you forget to switch off this setting.
• That's it.

If you have trouble receiving the E-Mail:

• Check your address. If you have entered some wrong E-Mail address, the message cannot reach your mailbox.
• Check your SPAM filter. Perhaps the SPAM filter has stored the message in your SPAM folder.
• If this all does not help, perhaps your ISP blocks our mail servers. We cannot help with that, this is an ISP problem then. Ask there.
• To make sure our servers send E-Mail, you can use another address, like some at mailinator.com. After entering this address, you will quickly see our answer there.
• Note that you cannot use public open mailers (like mailinator) as your identity. If you do so, it is likely that this identity will be blocked quickly, such that you loose your ID. In that case we cannot and will never help you, sorry.

If you have lost your E-Mail:

• Leave me a message telling me your trouble. Perhaps I can help you. But this is no promise.
• Note that the login credentials are bound to the data you gave to us. So if your data changes (your E-Mail or your OpenID) this creates a different account.

If you are puzzled where the registration is:

• 20.to entirely works without registration. You do not need to register, as registering and logging in is the same process here.
• If you use OpenID, the register process depends on your OpenID provider, not on 20.to.

Benefits from using OpenID:

• The only difference of OpenID is, that you can be automatically transferred back to the service which needed the login.
• As this information cannot be encoded in the link which is sent via E-Mail, you cannot auto-login to the service with it. This transparently works with OpenID.
• However there is a trick: If you get the login page, open the Login-Link with another Tab of the same browser. This logs you into 20.to. If you do not enter anything into the form and just submit it (this is: Click on "Login via E-Mail") you are transferred back to the service.
