You can use XPath or CSS to locate an element when there is no ID or name associated with a target element.

XPATH

//button/span[text()='Login']

CSS

 button>span.md-button-wrapper

Sample code

driver.FindElement(By.XPath("//button/span[text()='Login']")).Click();

driver.FindElement(By.CssSelector("button>span.md-button-wrapper")).Click();
