'Eingeben' (to enter / to administer) is a separable verb. The prefix 'ein-' comes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Ich gebe schnell mein Passwort ein.
I quickly enter my password.
The verb consists of the prefix 'ein-' and the verb 'geben' (to give). The prefix 'ein-' here has the meaning of 'into', which can be seen in all meanings: data into a computer, medicine into a body, or an idea into the mind.
Geben Sie den Betrag in den Automaten ein.
Enter the amount into the machine.
When you enter data, you often use the preposition 'in' with the accusative to describe the place where the entry is made.
Geben Sie den Code in das dafür vorgesehene Feld ein.
Enter the code in the field provided for it.
When administering medicine to an animal or a person, the person or animal is in the dative and the medicine is in the accusative. So the structure is: jemandem (dative) etwas (accusative) eingeben.
Die Mutter gibt ihrem kranken Kind den Hustensaft ein.
The mother administers the cough syrup to her sick child.
The meaning 'to convey an idea to someone' is elevated and is used mainly in written language or literary texts. It is rare in everyday speech.
Ein innerer Impuls schien ihm diese Entscheidung eingegeben zu haben.
An inner impulse seemed to have instilled this decision in him.
to give
'geben' and 'eingeben' are linguistically related, but they are used in different situations. 'geben' is general and means that someone hands something over or provides it. 'eingeben' is much more specific: you enter data into a device, administer medicine to a person or animal, or convey an idea to someone. The words can be confused because 'geben' is contained in 'eingeben'. In practice: use 'geben' for a normal handover. Use 'eingeben' for computers, forms, codes, or targeted administration of medicine.
