So it turns out that the answer was right under my nose and does not involve any deceit or hacking. Yahoo! provides an option for creating an account without a cellphone, but it isn't via the "Create Account" button.
On the sign-in page, there are a few options:
If you click the "Facebook" or "Google" button, you can sign in to Yahoo! using a Facebook or ...
Yes, you can create a Google account with your Yahoo email address—or any other email address, for that matter—if you follow this link: https://accounts.google.com/NewAccount.
Just to make things clearer because your question mixes some issues that might lead to confusion:
If you want to sign up for Google Plus with a Yahoo email address and you already ...
You can create (or, more specifically, I was just able to create) a Yahoo account without a mobile number by signing up with an existing email address. On the sign up page, click on "I'd rather use my own email address."
Now, of course, you need another email address that itself doesnt require a mobile number. There aren't many. On 7/29/2016 I created one ...
There's an option in Yahoo Groups to download Groups Data. I submitted a request but I haven't heard back yet so I can't verify if it's the solution to our problem: https://groups.yahoo.com/neo/getmydata
In the meantime, I like this script: https://github.com/IgnoredAmbience/yahoo-group-archiver (Thanks @tripleee in the comments).
This script downloads all ...
One obvious thing comes into my mind: the signature images are linked and not attached, so they need to be present on a public URL. They could of course let you upload and host it somewhere, but it's understandable that introducing such service alongside existing image sharing is not absolutely necessary.
According to the documentation, users need to opt-in to be able to find posts from NSFW blogs with Tumblr’s search:
What should I do if I don't want to see adult-oriented content?
Unless you actively choose to display explicit content, when you search for anything on Tumblr you will not see content from blogs that are marked as NSFW (not ...
Are you sure this mail is from Yahoo? Does it have the proper Yahoo ip-addresses in the headers?
It could be a forged mail, sent from elsewhere but appearing to be from Yahoo. Someone (some bot) got your gmail-address or guessed it, and using the same address for Yahoo is not a bad guess. Many people will have the same address on Outlook or Yahoo, just to ...
The ability to change ones profile picture went away when http://profiles.yahoo.com shut down in January, 2015. They've not introduced a new method to change your profile picture.
From Yahoo! help:
Update your Account picture
Yahoo Profile (profile.yahoo.com) no longer exists. But don't worry - your comments on various Yahoo properties didn't ...
We have confirmed, based on a recent investigation, that a copy of certain user account information was stolen from our network in late 2014 by what we believe is a state-sponsored actor. The account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (the vast majority with bcrypt) and, in some cases, ...
From Yahoo! help:
Sign in to your Account Info page.
Information you can change includes:
Personal info - Edit your name, address, phone number, alternate email addresses, or primary email address.
See this -> To change your listed mobile number in Yahoo Messenger.
If you happen to have an alternate email address listed with your Yahoo account you may be able to get a link to reset your password sent to that alternate email address.
See Recovering a lost or forgotten password on the Yahoo help pages for more info.
It's a measure to make it harder for spammers to create throwaway accounts. Unfortunately, like many security measures, it inconveniences innocent users more than the bad guys it's trying to stop.
There are lots of free webmail services out there. Certainly there's some that won't bug you for a cell phone number. (Have a look at Computers: Internet: E-mail: ...
It's not possible to create a new Yahoo account without listing a cell phone number. You could make up a cell phone number but when you enter the number Yahoo is going to send a text message to that number so that you can verify that the number actually belongs to you. If you can't verify the number you can't activate the account. Other options would be ...
I think you can create a Flickr with a google account.
That's what I did and I don't remember having to fill these informations. (apparently not)
After reading the terms of service
You can use Flickr for non profit, but it seems to be tolerated more than encouraged.
In any case you must be register as an individual.
Maybe using the company owner,...
Finally I got an email from Yahoo, and I just want to share the process:
Visit the link: https://order.smallbusiness.yahoo.com/order/reactivatedomain
Type in your domain name and click "Reactivate this Account".
Sign in using the Yahoo! ID and password.
Choose the desired options and click Continue through the steps that follow. Fill out your payment ...
You could try setting a new password by using the "Forgot Password" feature that'll send a link to alternative email address or phone number.
and if you don't even have access to those I'm afraid only customer care can help you.
The only way I can think of is to actually contact Yahoo! personally, explain the issue of you forgetting the password and ask them to verify you using the Gmail account that you have forwarded emails to.
For anything that requires cross-app integration, I use IFTTT which stand for IF This, Then That. It allows you to create recipes which are basically a set of actions consisting of a Trigger and an Action (to be taken on Trigger) for Channels which are apps that it supports (like Facebook or Gmail or WordPress or Date and Time, you get the idea).
