Why can’t I login into my Synology account?

Below are the reasons why you cannot log in and how you can resolve each issue as per the cause;

The account or password is invalid

You may have entered your username or password incorrectly. However, if you forgot your username or password, try the following:

You can have an administrator reset your password by going to Control Panel > User & Group (for DSM 7.0 and above) or User (for DSM 6.2 and earlier).

If you are the only administrator, reset the administrator login credentials.

This IP address has been blocked because it has reached the maximum number of failed login attempts allowed within a specific period

You can still sign in to your DSM account from a device with a different IP address. Once you are signed in, follow the below steps to remove the blocked IP address:

Tick Enable autoblock at the following locations:
For DSM 7.0 and above: Control Panel > Security > Protection > Auto Block.
For DSM 6.2 and earlier: Control Panel > Security > Account > Auto Block.
Click the Allow/Block List button.
Go to the Block List tab.
Select the blocked IP address and click Remove.
Click Delete in the pop-up window.
If you forgot your username/password or did not have a different IP address, reset the administrator login credentials.

Wrong verification code

If your verification code is incorrect, or you have changed or lost your mobile phone, you will not be able to log in. Therefore, it would be best if you also disabled multi-factor authentication as soon as possible.

Please sign in again when the system is ready. The LED indicators will indicate this on the front panel of your device.

The connection is expired

Your Internet connection may be unstable. Check if the Ethernet cable is properly connected, or try to access your account from a different network.
