Boric acid is not a protic acid.
It is a weak monobasic acid, behaving as a Lewis acid.
$\mathrm{B}(\mathrm{OH})_{3}+2 \mathrm{HOH} \longrightarrow\left[\mathrm{B}(\mathrm{OH})_{4}\right]^{-}+\mathrm{H}_{3} \mathrm{O}^{+}$
It behaves as an acid by accepting a pair of electrons from $\mathrm{OH}^{-}$ion.
