The “Invalid or missing CSRF token” message means that your browser couldn’t create a secure cookie, or couldn’t access that cookie to authorize your login. This can be caused by ad- or script-blocking plugins, but also by the browser itself if it's not allowed to set cookies.
To address this issue, follow these steps.
Chrome (Phone or PC)
Open Chrome Settings.
In the Privacy and security section, click on “Clear browsing data”.
Check “Cookies and other site data”, and uncheck the rest.
Click on “Clear data”.
Reload Chrome and log into your Ubidots account.
If this doesn't work, try disabling your installed extensions (only on PC). Browser extensions or add-ons can sometimes interfere with website functionality.
Firefox
Go to Firefox's top right corner menu -> Settings -> Privacy & Security menu.
Go to Cookies and site data section.
There are two options:
Click on “Clear data”, check only “Cookies and site data”, then click “Clear”.
Click on “Manage data”, search for Ubidots, click on “remove everything shown”, then click “Save changes”.
Reload Firefox and log into your Ubidots account.
Note
If this alone won't help, please enable third-party cookies in the menu mentioned in point 2.
Safari

Refresh the page and log into your Ubidots account.
