Is the word alfabeto the same in Brazilian and European Portuguese?

Yes

The word "alfabeto" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, vowels are generally more "open" and clearly articulated. When pronouncing "alfabeto," a Brazilian will likely pronounce the unstressed "e" more clearly. In Continental Portuguese, unstressed vowels tend to be "reduced" or "swallowed." This means a Portuguese person might pronounce the middle "e" much more softly, almost sounding like a faint "uh" or disappearing into the surrounding consonants, giving the word a more "closed" and rhythmic sound.
