VladimiraN.49154 (Customer) asked a question.
We would like to customize the default error message displayed on the Okta login form.
Is it possible to modify the default message?
Any guidance or relevant documentation references would be appreciated.
Thank you.

Hello @VladimiraN.49154 (Customer) Thank you for posting on our Community page!
The generic "Unable to sign in" error (often caused by invalid credentials) maps to a specific error key in Okta's backend: errors.E0000004. To change the text, you simply need to override this key in the widget's configuration.
For Customisation guides please see below:

If you require further assistance my advice would be to reach out via devforum.okta.com to take advantage of their expertise.
While we'll do our best to answer all of your questions here, this medium is more inclined towards Okta core products and features (non-developer work).
Thank you for reaching out to our Community and have a great day!
