There is a free subscription that you may enjoy, but it has quite a few limitations. If you think the Teamviewer software is the right software for you, then you should consider upgrading to their full version for which they charge a fee.
If you have lost the software you use to access Teamviewer, or if you cannot gain access via the normal route and you have lost your recovery code, then you should contact a forum mediator if you have a free account, and you should contact the customer service department if you have a paid account.
Only paid account holders may contact the customer service department and get an answer because access to support is one of the perks of the paid account. The forum is useful, but it is a very slow way to get answers and many questions go unanswered.
If you have recently been able to gain access to Teamviewer and now you cannot, then the system is probably down. The system itself does seem to have a problem with outages. The most commonly affected issues are ones involving the remote desktop or log-in.
This probably means that you are having Internet trouble and you should try again when you have a stronger Internet connection. You may also try restarting your Internet router. Another issue may be that your current device is not a “Trusted” device.
If you are still having trouble logging in and it is not your Internet connection, and it is not because the Teamviewer network is down, then it may be because your device is not trusted. Try logging in via your web browser to see if it sets off the “Trusted device” process.
If you are having trouble logging in, the “Trusted Device” process may help. Log in with your web browser on your desktop or your mobile device and idea may ask you if you wish to add this device as a trusted device. If you select yes, then an email link will be sent to you and you will be able to verify your current device as a trusted device.
When you add your current device as a “Trusted Device” with Teamviewer, the verification is saved as a cookie. If your web browser or app deletes cookies or blocks cookies, then it may cause you verification problems.
Obviously, if the email is not appearing in your Junk email folder, and if you have not accidentally blocked it with your email service, then it may be that the network is down and you need to try against later. There may also be a lag with the system and it takes a few hours for your email to come through. You should also try having the password sent from a different web browser and even from a different device to see if that makes a difference.
Click on “Extras” and then on “Options” and then on “Advanced” and un-tick the box next to the line, “Enable integrated system health checks.”
