Yahoo! Inc. (NASDAQ:YHOO) is phasing out Google and Facebook sign-ins from Flickr. Flickr e-mailed users of the photo website with notice that Google and Facebook IDs will no longer be accepted after June 30th.
Flickr users will have to create a Yahoo! account and connect it to Flickr. People with an existing Yahoo! ID that is connected to Flickr are encouraged to link it up before the end of the month.
Flickr integrated Google and Facebook logins three years ago to increase its user numbers. However, it seems like Yahoo! wants to use the popularity of Flickr to drive engagement within Yahoo! itself.
