  We review the current status of the determination of the strong coupling from
tau decay. Using the most recent release of the ALEPH data, a very
comprehensive phenomenological analysis has been performed, exploring all
strategies previously considered in the literature and several complementary
approaches. Once their actual uncertainties are properly assessed, the results
from all adopted methodologies are in excellent agreement, leading to a very
robust and reliable value of the strong coupling, $\alpha_s^{(n_f=3)}(m_\tau^2)
= 0.328\pm 0.013$, which implies $\alpha_s^{(n_f=5)}(M_Z^2) = 0.1197\pm
0.0015$.
