I have always liked Zoho products because they are always innovating and trying to enhance the user experience. I frequently use their products in my daily life, Zoho Writer being the primary one.
So today when I tried to log in to Zoho Writer, I found that there was also an option to sign in using Google/ Yahoo account. It first asks to sign in to the corresponding account and then you need to give permission to Zoho to access the details.
I am not sure when they launched this feature but it has to be quite recent since I use their products everyday and it could not have stayed away from my eyes for long. I don’t think this could have a great impact on the Google Docs user base which Zoho seems to be targeting, but reducing an extra log-in will certainly provide better user experience since users won’t have to remember another username and password.
