Zoho is creating values

For many decades I have seen companies come and go. Zoho appears to be doing everything that google is doing. I wish them luck on taking on google and reaching the same size. Zoho I have used several of Zoho platforms and it is always a pleasure to deal with Zoho. The name brings good experience and the after you experience Zoho you want to say nice thing about it. This is how relationships should be.

Immediately didn’t send notification and I’m locked out

I finally decided to go ahead and use multi factor and the very first time I tried using it the push notification failed to send and has since failed to send. Every. Single. Time.
My primary email account is now inaccessible. I had been able to sign in to my email online (not through the mobile app) until today, and now the sign in insists on sending a push notification that, guess what? Never arrives.
A separate Zoho email account gets push notifications no problem, but my primary account (the first one I tried using this on) is completely blocked. Same phone, same email app, same one auth app… While it’s nice to know that 2 step is in fact secure, it’s incredibly frustrating to be shut out of your own account simply by following the prompts to set up a security feature.

Don’t install! A frustrating circular trap!

I just waisted three days trying to set up a “OneAuth” authorization method on my pre-existing Zoho account. Spoke with a customer representative in India…very polite and kind, but could not help! Three options offered but unable to initiate any of them. Just loops you back to where you started. Destroyed a very simple but effective and useful two-factor login process that worked! Changed the number and type of characters used to login so that now it doesn’t recognize or accept your previous password! YOU ARE LOCKED OUT!! I have time sensitive emails that I am unable to access! Everything is programmed and automated…only foreign representatives and long, long, long waits! No remedies. Suggest finding other email and authentication providers…
