Not able to log into your Proton mail account? That can happen due to various reasons for example if you’ve forgotten your password, entering wrong account credentials, using Private Mode on Safari, issues with two steps verification, etc. To fix the Protonmail login issue, you need to find the cause behind it. So, the first thing is to check if you are trying to access ProtonMail on Safari browser Private Mode. ProtonMail is not supported with the Private mode of Safari browser, so in case it is enabled you should disable it first and then try again. Another thing that you can do is try accessing ProtonMail from another browser. If you can access your mail from another browser but not the current one, then the problem is not with your account but with the browser. Also, make sure the account credentials you are entering have no errors. You can reset your account in case you don’t remember the password properly.
