A number of Pokemon GO users have been experiencing difficulties when trying to sign up or log in. If you’re one those affected, you may have encountered the following error message several times for no apparent reason: “Unable to authenticate. Please try again.” However, you can rest assured that the development team is on the case and is trying to resolve these issues as soon as possible. Pokemon GO launched yesterday, July 6, as a free download for iOS and Android devices.
Pokemon GO users experiencing sign-up and log-in difficulties
Pokémon Blog 
I was able to play Poke GO for about 30 min before I was kicked. When I started back up the message shown above appeared. I have an IOS phone. None of my buddies with Android are having this problem. Pretty bummed about it. It’s been like this for 6 hours.

This feature is most likely coming in the future, but for now you can submit a request through the app by filling out a form to send to developer Niantic.

It looks like a number of people are still encountering this particular issue. Some are even reporting that they’re being locked out of their account after trying to log in via Pokemon Trainer Club several times. Have you tried signing in with your Google account?

!!!!THANK YOU!!!! for sharing that url! (apparently it’s a ‘.go’ address , but ‘.com’ redirects via searchengine). I changed my password through that medium (to same password, which was permissed), and enabled login to the app.
So I have been having this exact issue, on & off every 24-40 hours or so, since I started about a week ago.
(I use an Android device, specifically Samsung J7 on T-Mobile). Initially I created account via my GMail account, but shortly thereafter for several reasons (added PTO store possible perks, Pikachu as starter pokemon, and biggest of all my public display name, as well as chosen Gym team none/blue/yellow/red). Often upon attempting to log in to my PTL account, I got\get the “Unable to authenticate. Please try again.” message, despite (in absence of widespread server issues )immediate access to the account linked via my GMail account.
Although possibly tuning co-incidence (though at 6h & counting between “functional” and “buggy” not “altogether down”, not likely..) will rely on this truck in the future. Additionally: Does officially logging-out prior to disengagement from the appgame for an extended period of time (e.g. sleep or work) help, hinder, or neither hurt not benefit, future access to one’s account and/or systemic strain on the servers (ie if too many player’s all opt not to sign_out during overlapping span of time (?

After failing to load for some time, it says “failed to log in.” Try logging in with a different account. Except that doesn’t work either. It’s literally stuck here. It won’t do anything. Hitting “Retry” just repeats the process.

I googled it and was able to log in after this same problem. Put your phone on airplane mode, open app, turn off airplane mode and the app will
give you the option to log out. then you can log in again. It worked for me. Hope this helps you as well.
