How do I publish a blog, without having my identity revealed?One of the best techniques for keeping yourself anonymous is to use different Blogger / Google accounts, for different blogs. But, there's a downside to that technique.
I can't regain access to my blog, because I don't remember the email address!Sometimes, it's a bit more embarrassing.
I can't regain access to my blog, because I don't remember the GMail address!And here, we see blog owners who took the need for secrecy a bit far.
Regardless of whether one's Blogger account is based on a GMail, or a non GMail address, the backup Blogger account token - should one forget the account name or password - is the email address, that the Blogger account is based upon.
If you want to publish your blog without revealing your identity, that's fine - Blogger permits this - and even supports your need. In order to support this need, though, you have to allow them to refuse to disclose any personal details. Neither the account name - or email address, should you forget either, can be disclosed, without revealing your identity.
One of the reasons for using one's email address (Gmail, or non GMail) as your Blogger account name is so you won't forget the account name. If you forget your email address, you'll have worse problems than just inability to publish your Blogger blog.
Unfortunately, if you choose to use one "email address" to read and send your email, and a second "email address" (whether bogus, or genuine) to publish a Blogger blog, you are not as likely to remember your Blogger account name. That's a decision that you have to make. If you want to publish your blog anonymously, don't expect Blogger to gratuitously break your anonymity, later.
In this case, you're going to have to hope that you can supply your email account hosts - either GMail, or non GMail - with enough personal details (anonymity not possible, now) so they can restore your email account, and / or recover access to your Inbox - and you can open the Blogger account recovery message, and regain access to your Blogger account.
If you'e forgotten the backup email address of the active account, again, don't expect Blogger to tell you what you need to remember. Now, you'll have do do some research, and hope that you can find the forgotten email address mentioned in email, in one of your remembered accounts - or maybe in a friends email account.
This scenario will be intensified, when a blog is deleted for any of several different reasons - possibly including accused DMCA Violation.
And, if you're able to recover access, this time, consider using Two Step Verification, for future protection. Especially if you travel.
