login
The process of signing in to a computer system, website, or application, typically by entering a username and password.
Der Login ist fehlgeschlagen, bitte überprüfen Sie Ihr Passwort.
The login failed; please check your password.
'Der Login' is a noun from English. However, the related verb in German is not 'loginen', but the separable verb 'sich einloggen' (to log in).
Ich kann mich auf der Webseite nicht einloggen.
I can't log in to the website.
'Login' can mean the process of signing in or the data needed for it. When it refers to the process, you might say, for example, 'der Login dauert lange' (the login takes a long time). When it refers to the data, you say 'ich habe meinen Login vergessen' (I forgot my login details).
Der Login war erfolgreich.
The login was successful.
When 'Login' means the access credentials, it is often used with verbs like 'eingeben' (to enter), 'vergessen' (to forget), 'ändern' (to change), or 'speichern' (to save).
Ich muss meinen Login ändern, weil ich das Passwort vergessen habe.
I need to change my login details because I forgot the password.
account
'der Account' and 'der Login' both belong to the use of websites, apps, or software. 'der Account' is the user account itself, meaning the personal access to a service. 'der Login' means either signing in to this service or the login details for it. Learners easily confuse the words because you often need a username and password for both. But an account can exist for a long time, while a login is a process or the details for that process. So you create an account and use the login to sign in.
Der Login funktioniert nicht, weil Anna ihr Passwort vergessen hat.
The login is not working because Anna has forgotten her password.
