'Einchecken' (to check in) is a separable verb. In a main clause, the prefix 'ein' comes at the end; in a subordinate clause, the verb stays together; and in the infinitive with 'zu', 'zu' comes in the middle.
Ich checke morgen früh im Hotel ein.
I am checking in at the hotel tomorrow morning.
The word was taken directly from the English 'to check in' and adapted into German. It consists of the separable prefix 'ein-' and the verb 'checken' (to check).

to register / log in
'anmelden' and 'einchecken' both mean that you register somewhere or gain access. 'anmelden' is more general: you can sign up for a course, log in to a website, or officially register someone. 'einchecken' is used especially upon arrival, for example at a hotel, at the airport, or at an event. The words can be confused because checking in often also involves checking a registration. When it is about travel or arrival, 'einchecken' sounds more natural; in most other situations, 'anmelden' fits better.
