Authorization Token
Make sure you have received an email with your personal single-use authorization token. It looks like this:
If you have not received an authorization token yet, sign up.
You shoud did it without adblocker on this page or try to incognito mode.
If you use the same email address to request multiple auth tokens, you will get the same one the next time, only if you have not yet claimed/used the last one to sign a node identity before. Once you have claimed a token, you can again use the same email address to request a new one for another node (which of course should be running on its own IP and location)
By using your authorization token, you agree to the Storage Sharing Terms and Conditions.
