@Vaibhav.phale1 There is a balance to find between security and privacy: when you ask a mail, you ask people to provide a private information (or a burden to create a new mailbox separated from the main address). Did you take that in consideration in your analysis and what are your thoughts about this?

It seems that setting $wgEmailConfirmToEdit = true is a way to achieve this, but I'm not sure if this exactly matches your requirements.

@Vaibhav.phale1, are you requesting this for Wikimedia projects, or MediaWiki in general?

@MaxSem, I only request that Wikipedia have to make email I'd or other user verification detail as mandatory field. So they can easily recover their account if they forgets the password. Because, nowadays peoples are having multiple accounts on different websites. They unable to memorize all user I'd and password.

I tried to clean up the description and title for grammar and comprehensibility.

There seems to be two or three requests here:

1. Make the email field mandatory during account registration, or provide a configuration option to do so.
2. Add the ability to set a mobile phone number as a property on the user account, along with the ability to use this number for password reset. Then change #1 to make it mandatory that either email or phone number be specified.
3. (maybe) Enable either #1 or #2 on WMF wikis.

#1 would be easy enough for someone to do, and simply having a configuration option for it doesn't seem very controversial.

For #2, adding the ability to input a mobile number would be easy enough (assuming we store it in the user_properties table rather than adding a column to user), as would changing the behavior of the configuration option in #1. Adding it to CentralAuth (SUL) would be somewhat more difficult, since there's no globaluser_properties table yet (see also T16950). Actually using the mobile number for password reset would require integrating and configuring an SMS gateway service, which might be difficult and/or expensive.

#3 would be an easy configuration change once the option exists, but would be a potentially significant policy change that may need significant discussion.

That's why password managers exist.

OK @Anomie sir. My intense is only to make Wikipedia account user friendly. So, users can able to reset their password easily. But wikipedia policy doesnt allow it to make email id as a mandatory fireld. You are also correct. Anyways, Wikipedia finds the better solution for this. (And sorry for my poor english). 😅😅😅

which doesn't make it a requirement, but does make no-email an option you need to actively confirm and warns you of the consequences.

T159837: Introduce confirmation step if user tries to register without email now has a patch, for those interested.
