Verifiers SHOULD NOT impose other composition rules (e.g., requiring mixtures of different character types or prohibiting consecutively repeated characters) for memorized secrets. Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically).However, verifiers SHALL force a change if there is evidence of compromise of the authenticator.

ASD encourages the use of longer passphrases without complexity ... ASD also encourages system owners to consider whether passphrases need to expire or not
Password expiration policies do more harm than good
Password guidelines for administrators... Don't require mandatory periodic password resets for user accounts

Stop frequently changing passwords, for example each month, as it leads to poor passwords being created

ACSC recommends they be at least 13 alphabetic characters. A number of randomly chosen dictionary words would satisfy this requirement

Favour length over complexity. Eliminate password expiry.
https://www.ncsc.gov.uk/articles/problems-forcing-regular-password-expiry
The NCSC now recommend organisations do not force regular password expiry. We believe this reduces the vulnerabilities associated with regularly expiring passwords
As a general rule, get your users to create a strong initial password and only change them if there are pressing reasons, such as a personal data breach.

Use long passwords. Do not force users to mix and match different types of character sets.

While some experts began questioning this practice at least a decade ago, it was only in the past few years that published research provided evidence that this practice may be less beneficial than previously thought, and sometimes even counterproductive.

changing passwords every 90 days gives you the ILLUSION of stronger security while inflicting needless pain and cost to your organization

Passwords should be changed only when there is reason to believe a password has been compromised

Password Aging Is Widely Advocated but Rarely Worthwhile
Password Aging Can Burden an Already-Weak Authentication Method
Password aging is commonly advocated as a necessary standard; however, it is difficult to identify cases in which it has improved the level of security or prevented an incident. In many cases, it can induce user behaviors that may actually create security risks.

In sum ... the burden appears to shift to those who continue to support password aging policies, to explain why
