# Unable to login to the portal

This article addresses the most common issues, regarding logging on to the Calculus portal, and explains how to resolve these issues.

## Verify the website address

Check your browser’s address bar, and make sure you are trying to login to the Calculus portal, which is located at [https://portal.calculus.group.](https://portal.calculus.group.) It is possible you are visiting [https://my.calculus.group,](https://my.calculus.group,) which is a different portal and does not share the same credentials. The login screen should look like this:

## Check your credentials

Always log in with the same e-mail address used to register your account. Make sure you enter the correct password. We recommend you use a password manager application or web service to store your password, so forgetting it is a thing of the past. If you forgot your password, you can set a new one by clicking on **I forgot my password**, below the login button. More details on this in the following article: [Reset password](https://docs.calculus.group/docs/reset-password).

Please note that after 10 consecutive failed login attempts, your account will be locked for 30 minutes. This is a security feature and cannot be circumvented.

> [!WARNING]
> Attention!
> 
> All new accounts have to be verified, before they can be used. On creation of a new account, a verification e-mail is sent to the user. This e-mail contains an activation link, and the account has to be activated within 7 days.
> 
> If you can’t find this activation e-mail, please check your spam-folder. If you still can’t find it, or the 7 day activation period has expired, please contact the project’s account manager, verify your e-mail address, and request to be re-invited.
