This is definitely a false problem. Quantum computers will not appear in development for 20 years, and its operating costs are very high. It may take several years to crack a password. So you don't have to worry.

In 2015, the US National Security Agency (NSA) announced the plans for the
transition to post-quantum cryptographic algorithms: Unfortunately, the growth of
elliptic curve use has bumped up against the fact of continued progress in the research
on quantum computing, which has made it clear that elliptic curve cryptography is not
the long-term solution many once hoped it would be.;

In 2016, IBM provided the first cloud-based quantum computer, IBM Q, with five
qubits, accessible to anyone who wants to practice quantum programming;

In 2016, Intel engineers announced the work on a quantum processor with millions
of qubits;

In 2016, Google Chrome developers implemented the post-quantum key exchange
algorithm New Hope and in 2017 Google predicted the commercialization of
quantum technology within the next five years;

In April 2018, the developers implemented the post-quantum algorithm of the XMSS
digital signature for the OpenSSH 7.7 update;

In June 2018, Microsoft added post-quantum key exchange algorithms and
signatures to their OpenVPN fork.

They are worried...
