DNA Corporate Customer Login Has Been Renewed

Corporate services (e.g. YritysDNA self-service):

• You will always log in using your personal DNA Account and two-factor authentication.
• The old login method will be discontinued on 21 May 2026.
• Your username will remain unchanged.

Virtual PBX service:

• You can continue to log in via the old login view using your current username and password.
• The old login method will remain available for now.
• If your username is linked to a personal email address or phone number, you can switch to the new login via the “Switch to the new login” option in the login view.
• Once activated, the same login credentials can be used across the Virtual PBX service and other services such as YritysDNA.
• Your username will remain unchanged

The login renewal does not affect:

• DNA Call or DNA Business apps
• DNA Messaging service
• Softphone

You can continue using these services as before.

No. This change does not apply to DNA’s consumer services, including the OmaDNA app.

If your company uses consumer services, they can still be managed in OmaDNA as before.

When signing in via the new login view for the first time, you must:

• Create a new strong password
• Enable two-factor authentication

To use two-factor authentication, your username must be linked to a valid email address or phone number for receiving verification codes.

Two-factor authentication is required at every login. Your username will remain unchanged.

1. Go to yritysdna.dna.fi
2. Enter your email address and select Next
3. Create a new strong password
4. If this is your first login, accept the terms and conditions
5. Choose your preferred authentication method (email or SMS)
6. Enter the one-time verification code and select Confirm

You have now activated the new login and two-factor authentication.

For future logins:

• Use the same authentication method, or
• Add an additional method

We recommend enabling both email and phone number.

Managing authentication methods:

1. Log in at yritysdna.dna.fi
2. Enter your email address and select Next
3. Enter your password
4. Select Choose another authentication method to continue
5. Complete authentication using your current method
6. Add a new method by selecting the “+” icon (you can remove a method using the bin icon)
7. When adding a new method, you must verify it via two-factor authentication

Two-factor authentication combined with a strong password provides a significantly more secure login method:

• It reduces the risk of data breaches and unauthorised access
• Strong passwords are more resistant to compromise

Together, these measures strengthen your organisation’s cybersecurity baseline.

The new login requires two-factor authentication, which means that your username must be linked to a personal email address or phone number.

If this requirement is not met, the new login cannot yet be used. For this reason, both login methods are currently supported in the Virtual PBX service.

If your username includes a personal email address or phone number, you can switch to the new login.

If you have already enabled the new login in other DNA corporate services (such as YritysDNA), you can use it directly in the Switchboard Service. The same password applies across both services.

From 21 May 2026, YritysDNA requires the new login method, including:

• Two-factor authentication
• A strong password

If you are still using the old login in the Virtual PBX service, the same password cannot be used for YritysDNA. You will need to log in to the services separately.

If you are using the old login method in the Virtual PBX service, you cannot directly access YritysDNA with the same login session.

YritysDNA requires the new login platform, which always includes two-factor authentication. Therefore, separate logins are required.
