With this plugin you can now add a real log in/logout item menu with autoswitch when user is logged in or not. 
Nonce token is present on logout item. 
2 titles, one for ‘log in’ and one for ‘logout’ can be set up. 
Also, you can set the redirecion page you want, just awesome.

Login Logout Menu

This plugin (still) works great.

However be aware that it's not compatible with PHP 8 or newer, the latest PHP version this plugin will work with is 7.4. This is due to its use of create_function, which has been deprecated since PHP 7.2 and removed as of PHP 8. This should be replaced with an anonymous function, which is easy enough. But I haven't tested this myself, so I don't know if that's the only incompatibility with PHP 8+.

Works great, but...

You can now add a correct login & logout link in your WP menus.

The core functions’ documentation states that nonces, small validity tokens used throughout WordPress core and other plugins, have a lifespan of 1 day, however they can last as little as half that time. For common usage that may not be a problem, but if that lifespan is relied upon in any meaningful way, inexplicable failures can occur. For example, filters that shorten the lifespan may randomly make it difficult to complete some tasks before their nonce expires. Very long lifespans, such as those set by many caching and SEO optimization plugins, can result in forms and other actions suddenly breaking before the cached content expires and new nonces get generated. Imagine a contact form that’s cached for a week but stops working after 4 days, then starts working again if that cache is cleared. A cursory search for terms like <code>caching nonce expired wordpress</code> yields many results for relevant problems.
This plugin guarantees a nonce will last at least as long as it’s intended to, but up to ⅛ of a lifepsan more. By default, this means a nonce will last from 24 up to 27 hours, rather than anywhere from 12 to 24 hours. It was created because changing the behaviour of such old code was deemed inappropriate (in <a href="https://core.trac.wordpress.org/ticket/53236" rel="nofollow ugc">ticket #53236</a>), given the functions are pluggable.

Noncensible

Provides sensible replacements of default nonce generation functions to more accurately reflect their expected behaviour.
